It's 11 o'clock - the exam is over! How did everyone go? I want to get an idea of the overall response to know how the kids I tutor really went!
-
I think it went pretty good :) better than expected. How did everyone else go?
-
Yeah wasn't bad at all. Couple tricky little things, but I think I did alright, so that's all good lol.
-
Seemed like a pretty easy exam, in my opinion.
Does anyone think the marking will be more strict because it was easier (and hence people will have performed better as a whole)? I hope they don't :/
-
Hope not lol
-
My friends at school thought it was pretty easy..
-
it was yer pretty easy. Some dodgy q's though like the cholesterol one but yer i got over it :) i know i lost a mark for the mc were it goes what is the role of lipids, i put transported by rough ER by apparently it's energy suppliers or some crap.
ehh anyone got the answers to mc's?
-

ehh anyone got the answers to mc's?
are u sure? coz i put down energy storage.
once all the glycogon is used up. the body then uses lipids for energy..
i know a lost stupid marks. i cant believe i did it.
the question where u had to write the complementary code from DNA to RNA.
do u know what dumbass me put?
Ok. I knew T gets changd to U.
so whenever T needed to be changed, i put u.
Now. Retard me. Completely completely, completly forgot A stays the same.
So whenever A come. i put u.
so my complementary strand ended up looking like
GUUUUUUCGUUUUUUUU
Something like that. kill me.
it was onli worth one mark anyway.
oh well
i also lost points where there was the diagram of the different cells near the end, and u had to state which cells were what. fuck man. they all looked the same.
all i got was B cells :'(
there the onli two parts i had fucked up on major.
so hopefully i got the majority of everything else correct.
how'd others go ?

Lipids dont store energy. They are used as energy, yes- but they dont store them. Hence, they supply energy. Your reasoning is correct- your answer is wrong.
EDIT: Shortened Paul's quote :)
-
kill me lmao.
den what was the correct answer.
-
does anyone have the answers for the mc questions..??
-
does anyone have the answers for the mc questions..??
how we supposed to have the answers to the MC - we just did the exam 2 seconds ago. LOL.
-
Loved the Micheal Jackson question and the short answer question about DNA
The question about the immune system, I had no idea and guessed B cells, T cells and then 'T Helper Cells'
Really fizzled out, but I used multiple Sclerosis for my Auto immune diease and explained it pretty well.
What did you guys put down for the donor question about the boy needing a transplant, I had no clue so chose the neighbour as his antibodies were the closest.
-
what did everyone get for the last question about chemical number 4?
-
yeh i chose the neighbor coz his was the closest
-
did u hav to explain it? it just said to talk about autoimmune disease in general yeh?
-
same here.. i chose the neighbour. had no idea what to write for the last short answer question about why the drug was more effective, any ideas..?
-
i just talked about autoimmune diseases in general..the not recognising self and non-self cells stuff..
-
you know how it had that triangle thing, i wrote so another chemical could attach to it so i can break it down so it doesnt acuumulate.
-
yeh so did i. coz it didnt say to specificaly talk about the disease you chose true?
-
what did everyone write for the trna questions?
-

amm i used MS as well.
yeh i chose the neighbor coz his was the closest
same
-
what did everyone write for the trna questions?
carries anti-codon to ribosomes to attach to complementary codon on the mRNA in codons.
so wait, what's the right answer to the lipid q?
-
i wrote it translates the code on the dna. thats wrog isnt it. shittt.
for the lipid question i did it stroes energy
-
what do u think was the hardest question?
-
The answer to the lipid question was A.
Lipids are a form of energy storage.
-
yeh dats wat i got
-
The answer to the lipid question was A.
Lipids are a form of energy storage.
yer i got that wrong, stupid me i put that first than i crossed it out and put D. i think that's the only MC one i got wrong.
someone put up the exam and answers.
-
was pretty good, except the experiment question i forgot to say expose both groups to wasps argh
hated the question about the breathing neuron thing asking why the circut is good, apart from that was pretty alrite
-
Overall was pretty nice exam, loved the question on naming bits of clonal selection :D
-
was pretty good, except the experiment question i forgot to say expose both groups to wasps argh
hated the question about the breathing neuron thing asking why the circut is good, apart from that was pretty alrite
for the circut one i put the first as sensor
the second as interneuron?
are those right?
-

I think studyhound was referring to the rhythmic breathing question. For the golf ball response I had sensory neurone and effector
-
wasnt it a receptor?
-
i think it was receptor cause the sensory neuron was the actual neuron not the muscle itself that has the receptors. And i think it was interneuron since it joined with the sensory and the effector and it went through the brain.
-
i did motor neuron coz it was sending the impulse from the CNS to the effector
-
who puts up the answers to the exam?
-
What did you guys do for that picture one .. the one with the sugar, phosphate and base?
I just put them together like a puzzle, hahaha.
Also, is DNA a polysaccharide in animals ?
-
i did motor neuron coz it was sending the impulse from the CNS to the effector
but it was still in the brain and then it linked to the one outside the brain.. ehh we'll see how it goes. i hate talking about the exams after i do them.
-
What did you guys do for that picture one .. the one with the sugar, phosphate and base?
I just put them together like a puzzle, hahaha.
Also, is DNA a polysaccharide in animals ?
DNA is a type of nucleic acid. Glycogen was the answer you were looking for.
-
glycogen is a polysachharide. you had to join the phospahte to the sugar and then the sugar to the base
-
i just wanna see the answers to c how i went. omg im scareddd
-
Oh no! That's already 2 questions wrong :(
Did many of you guys guess questions?
-
ey mandy wat skool do u go to?
-
i tried to chose the best answer.
some of the short answers..to be honest i just wrote watever for like 2 of em.
-
I WAS hoping for an A, but now I'll lower that to a C.
And go curl up and die.
-
yeah i was tlking about the breathing one, lol i thought it was hard aha someone get this dam exam up even jst mc's
-
omg..these questions i've done all before.. but they were at the start of the year.. that's what you get for preparing ahead...... and i forgot... most question i wrote crap..... i know how strict the examiners are.... and probably get alot wrong.....im so freakin depressssssssssssssssssssed... i 've got chem exam tomorrow and i can't study.....MC was hard.. which is more heavier.... mitochondiri or ribosomes????????????????????????farkkkkkkk.. i can't study for chem!!!!!!!!!
-
haha i got chem 2moro too... aww for that question i did the nucleus as the heaveist because everything happens in there
-
ok good i have people in the same boat as me so it isnt so bad hahhaa.
ok. for the antibodies for the dad i think it was.
we never covered that in class, so i put the neighbour, closest to his antibodies i just guessed.
where it said state an autoimmune disease i also put multiple scelrosis.
im sure the question said to explaim autoimmune disease in general, which i did. i didnt mention what happens in multiple sclerosis..
ummm.
also for that gay as golfball question. that was really hard coz it wasnt the most clearest picture to decipher.
trying to remember now, i think i put sensory neuron and an interneuron, coz i dont believe there was an actual pathway of the motor neuron occuring. i remember it shows the sensory neuron going to the brain, and then at the brain, there was the interneuron.
oh god. it was fucked.
hahaa.
-
how do u get the answers for the frkn examm
-
oh and for ther very last question about why drug 4 would be most effective.
i had less than 2 minutes to write my answer before pens down.
so first thing that popped into my mind i just wrote.
even though it was wrong.
drug 4 would be most effective because again, it has the compliment receptors, and there is an active site, which another drug can be created to fit into the active site to inhibit it.
some shit like that i wrote. hahahahahah!
-
how do u get the answers for the frkn examm
think we have to wait till the end of the year or next year. baaaaaaaaaaah
-
u know for the glofball onee... i wrote receptor. coz its ppointing to that thing in the eye yeh? sensory neuron is that actual line thing thats connected to the receptorr.... yehh... anyone agree oor nahh im just blabbing onn
-
i thought it was effector because it was pointing to the muscle controlling the eye, the actual stimulus would be recepted in the eye and transmitted out of the eye via the optic nerve?
-
im looking at it bakwardsss lol.... ur right veno
-
i feel so shit thinking about that exam.. i honestly screwed up the whole rythmic breathing question and have no idea about the last one..
-
I SERIOUSLY WANNA CRY NOW!!!!
-
if u get higher than a B, il be fineee.. coz it looks like i wont be getting higher than 80% lol
-
I also got effector!
I ALSO WANT TO CRY. I HAD A SOOK JUST BEFORE.
-
lmao.. okaii we should stop stressingg!!!
i got another exam 2moro..chemistry!!!
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
-
:'(
-
So I know for next time...which practice exam do u think was the best to do ..
-
so what is the overall answer for the golfball question kids?
-
what did u guys writw for the cholestrol question?
-
Lipids dont store energy. They are used as energy, yes- but they dont store them. Hence, they supply energy. Your reasoning is correct- your answer is wrong.
Lipids DO store energy!!!
Adipose tissue => 3 carbon molecules => respiration
they store DOUBLE the energy per gramme of carbohydrates
They certainly do not travel through the RER, as they are synthesised on the SER
-
For the cholesterol question i had two points
-Cholesterol prevents cell membrane liquidification at high temperatures
-Cholesterol prevents cell membrane solidification at low temperatures
-
Gah, the more I think about it, the harder this exam seems. I would have lost so many marks :( And I had a chemistry class in the afternoon and I couldn't concentrate, then I got 62% on it and I was so angry. I don't think chem is going to be too good tomorrow. :(
-
YESSSSSSSSSSSS WHOOOOOOOOO HOOOO WOOOHOOOOHOHOHOHOHOHOHOHOHOHOH
I GOT DAT RIGHTTTT AYAYAYAYAYAYAYAYAYAYAYAYAYAYAYAYAYAYAYAYYAYAYAYAYAYAYAYAYAYAYA

cholestrol questionnnn
-
For the golfball question, was 1. receptor and 2. connecting neurone
? im sure 2. was connecting neurone as a neurone is a brain neuron and it was in the brain, but now im doubting whether or not 1. was the effector or the receptor and was the receptor actually the retina/optical nerve junction
-
I had 2 as connecting neurone too but 1 was the effector, it was pointing at the muscle that controls the eye lid and therefore the response (blinking at the ball).. not the eye itself
-

? im sure 2. was connecting neurone as a neurone is a brain neuron and it was in the brain, but now im doubting whether or not 1. was the effector or the receptor and was the receptor actually the retina/optical nerve junction
same
-
so 1. was receptor? now that im looking at it again it seems more logical that 1. is actually the effector as it looks muscle-y
-
hey what did you guys put fir the question about leaves?Did species x shed their leaves?
???
-
so 1. was receptor? now that im looking at it again it seems more logical that 1. is actually the effector as it looks muscle-y
yer 1 looks like an effector but i know 2 is an interneuron
-
lol just had another look at the eye question. Still not 100% sure on answer but notice the brain looks like a face?
http://img521.imageshack.us/img521/3770/smilebrainj.png
-
im pretty sure 1 is effector since the retiner is the receptor and 2 is the interneuron. I think i got 1/2 for that. LOl it does look like a face.
-
hey what did you guys put fir the question about leaves?Did species x shed their leaves?
???
Yea, I said they dropped their leaves as they changed colour and died cos couldnt photosythesise using alpha or beta chlorophyll anymore and i talked a little about abscicic acid dropping the leaves off
-
What does everyone think the A+ cutoff will be? Also, approximately how many marks per exam have people lost in the past and still got a 50?
-
i think the A+ will be much less than last years that's for sure. the 2008 exam was a walk in the park compared to this. FUCK THE CENTRIFUGE Q WAS REEEEEETARDED THE WORDING WAS STUPID!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! i put C :)
-
I think i did too hard.. i looked at that and was like why.. wtf!
and yeah it has to be lower then last years.. last years was ridiculously easy :S
-
http://www.vcaa.vic.edu.au/vce/statistics/subjectstats.html
Then choose a year and then Section 3: Grade Distributions for Graded Assessments VCE
Let's you see a breakdown of grades.
-
Anyone know the percentage of 'T' in the DNA or somehtin :S
T_______T
soo harddd
every1 seems to ahve done good...
NOOOOOOOOOO! i get scaledd down :'(
-
20%?
-
I got 20% as well.
-
i ended up with 20% because there was 30% of C and the same of G.. then 40% left over and there are equal amounts of T and A.. so 20% each..that make any sense?
-
I got 20%, though all my friends put down 30%
-
Darn it, I just said that the cholesterol was tighly packed together and provided fluidity. eeek!
-
How about the very last question? I went with higher surface area, but I am sure that is wrong.
-
When do we get our results BACKKKKKK??????????????????????//
-
i have no idea
-
u know the answers someone put.. der not all rightt yeh
-
for the last multiple choice quest abt proteomes, was the answe the option with the proteases involved in process q?
-
for the last multiple choice quest abt proteomes, was the answe the option with the proteases involved in process q?
your making me dreadddd! i think i did crap T___T
hopefully *no offence* every1 did crap and we get scaled up ^^
-
Fady daniel, refer to your question on pg 3 for my response.
im not 100% sure its right, but yeah. haha. made sense at the time.
results i believe 4th August.
rasangi - i put b.
Step R involves the joining of proteins to form polypeptides.
this is what the two boxes say..
Mixture containing all proteins of an organism.
Mixture containing all peptides of an organism.
again i dont know if its 100% right. but thats what appealed to me at the time.
-
Why on earth was the donor question the neighbour?
-
Why on earth was the donor question the neighbour?
it was wasn't it... cause when u comapre it they r the most simluarr
-
When do we get our results BACKKKKKK??????????????????????//
in mid August i think
-
For the leaves question ( sheding etc.) I put that it didnt shed because the chlorophlly didnt decrease. Dont know why.
-
that was the one question on the exam i couldnt answer.
i didnt even get what it was asking.
lmao.
-
Hmm examiners take the first answer before the second,
-
:O do u think this year the exam will get scaled up ><
I HOPE IT DOESS!
cause by the looks of it i might be gettinga C+ :(:(:(:(:(
-
I hope it does!
-
haha, the michael jackson one made me laugh. i read it and tried not to laugh.
i had a mental blank with question 7 a-c, it was easy but for some reason i just went blah...
overall though it wasn't as hard as i thought it was. same here with the donor Q, i went
with the neighbour for the same reasons because his matched the most.
-
quit yo jibber jabbin
-
i agree andrew
leaves question could go both ways probs - dependent on justification
and yes this exam was a bitch - testing peoples problem solving skills rather than biol in most cases
however i think this is a result of the 06,7,8 ones being quite similar in content
you know - rational drug design this.. - signal transduction that - enzyme reaction rates etc. just the basic conceptual stuff
so in order to stop the A+ cut off being absurdly high this year they simply HAD to make a realtively difficult exam in comparison to others
anyway, thats just my opinion ..
-
and yes this exam was a bitch - testing peoples problem solving skills rather than biol in most cases
Testing problem solving i.e. application of concepts is the whole point of short answer. What they failed to do this year though was give enough stimulus information for you to work from since you had to make plenty of assumptions. Also, shitty diagrams didn't help, and there were numerous ones this year. Bring back the old diagram artist D:
-
SCALE UP!!! i pray

yeah thats what i sort of mean - like i know biol is all about applying knowledge to unfamillar situations
it was just these situations were really vague/crappy'ly presentend/or just ambigious lol
-
SCALE UP!!! i pray
Scaling has nothing to do with the difficulty of the exam. It depends on how well the Biology cohort does in their other subjects.

I agree with you.
Too ambiguous to call.
It could work to our advantage after their discussion as to what will and will not be accepted though.
Any answer could pass as the right one with justification.
To be honest, I didn't find the exam to be hard, I thought it to be very, very easy in comparison to some of the practice exams.

1. When do we know what mark we get? i know that you will be given A+, A etc but can we get an exact mark?
2. Do we ever get to look at our paper again and see which ones exactly we got wrong???
3. What exactly is an A+, is it >80% ??
4. what exam score is needed for a study score of 45 or over
thx.
-

1. You can get a statement of marks for an exact mark ( have to pay for this)
2. You can pay to look at your paper but there are no marks/comments on it
3. Unknown
4. Probably High a+ one exam, mid a+ the other. ( guessing here)

4. what exam score is needed for a study score of 45 or over
thx.
1. You can get an exact mark if you pay for a statement of marks. Its around $8.50 I think.
2. If you want to do this, you will have to pay to inspect your paper. I think its about $16.
3. The cutoff for an A+ changes every year, depending on how well everyone else who did the paper performed. If its a hard exam, the A+ cutoff is usually lower than if the exam was easy.
4. Dependent on many factors, such as SAC marks and such, but as a very general rule you would need mid-to-high A+s for exams.
-
I would like a different chem exam instead D: Rather a redo of that than bio.
Yes you need an A+ for all three grades for over 45.
-
i did so much mistakes... stupid mistakes... but hey i tried my best and that's all that matters... i don't wnat to see if i got this write or that wrong..... whatever happens , happens for a reason i guess... pls remind me this when i get a shit mark
-
Yes, my friend got two As and an A+ last year and she only got 38, her parents wanted to make her take bio again to get over 40 but she convinced them to let her drop it at the beginning of the year.
She makes me fear for my marks! She is really smart!

For the golf ball question, 2 is definitely a sensory neuron.
(http://i73.photobucket.com/albums/i205/mebrunette/Neurontypes.gif)
See how the structure of the sensory neuron is identical to the one pictured here?

agreed :)
-
i think that questions a bit dodgy, but i think its connector/interneuron
I think i read somehwere that effector neurons are connected to sensory neurons by interneurons.
If it is sensory neuron, then that means it would be connected to the effector neuron directly...
-

True.
As for the diagram, that doesn't really affect any of the 'arguments' listed here. I really have no idea =\
-
The question still remains however, why would an interneuron be connected to the retina (a receptor)?
-
My interpretation was that the first part is definitely a sensory neuron, but that the right branch of it could have been the interneuron (hence why the arrow only points towards that branch). And yes, I know that the interneuron needs its own cell body, and I've made that clear in the list of 'arguments'.
-
I see your point - I still think my way is right, but your interpretation could be argued pretty well!
-
on a slightly different note:
Is there a set marking scheme that biology assessors stick to?? (e.g such as dealing with spelling mistakes, different interpretations of the question and other aspects..)
Are the assessors generally well qualified for their role or well-knowledged? (just a bit worried cause on the thyroxine question i put that it has an intracellular receptor, which i read somewhere else and the assessor may not know that)
-
the guy at those TSFX lectures is actually the teacher at my school, and i reckon writing out "Adenosine triphosphate" instead of ATP, or "human immunodeficiency virus" instead of HIV is just dumb and a waste of time. But for school sacs i always listen to what my teacher says (as they are marking.)
im pretty sure theyll accept NADPH as an answer. THe question said "Name one of these charged carriers." - they ahve already told u in the question that these carriers charged/loaded so i dont think theres any need to say that in ur answer...
-
I disagree with you, qshyrn - if they say NAME the molecule, they are asking you implicitly to write out the whole name. Although they usually end up accepting both, they always mention it in the assessment report that they wanted students to write it out fully.
-
o ok..
i can understand if they are asking you to NAME a specific thing, but if you need to give an explanation answer, then i dont see the reason of incorporating "adenosine triphosphate"in your answer instead of atp.
btw, with that charged carrier question, i dont think anyone knows what NADP stands for (i dont even know if were even meant to know it.)
- i dont go to those TSFX lectures
-
I see your point - I still think my way is right, but your interpretation could be argued pretty well!
Well actually, I'm more inclined towards thinking it's a sensory receptor as it doesn't rely on assuming that the diagram is screwed up; just that it's really really poorly drawn. I'd say this is more likely as VCAA isn't likely to let mistakes pass through into the exam.

Spelling mistakes are covered by a rule that just states people need to be able to write out a word which at least phonetically sounds like the word they're trying to get. So writing glicojen instead of glycogen will get you the mark, but writing glucagon which is actually much closer in terms of spelling will make you lose the mark. Of course, if it doesn't resemble anything at all, you'll lose the mark too. Also, different interpretations of the question are covered by the meetings the examiners have. As for the thyroxine thing, why's that relevant? The question asked for TSH, not thyroxine. Sorry to say but you'll get it wrong regardless =\

At the end of the day, the exam is all about showing off your knowledge in the subject to the examiners. If you write out the full name of a chemical, such as ATP, you are showing the person marking your exam that you aren't simply memorizing acronyms, but rather have a greater expanse of knowledge on the subject. That's just my opinion - if you can show off to the assessor a little bit, I don't see why you wouldn't do it!
-
It was the one after the TSH one, about thyroxine on the brain tissue +testes
-
It was the one after the TSH one, about thyroxine on the brain tissue +testes
Oh right. Well for 1 mark, you could have just gotten away by saying they didn't have the specific receptor required anyway. No need to go in depth, but well, look below and I'll elaborate on possible benefits of that.

You aren't simply memorising acronyms; you're simply memorising entire names now =P I don't think this conveys a greater knowledge of the subject, just a greater will to memorise stuff, rather than true understanding. As for whether you need to or not, well put simply, pretty much no. You won't gain any more marks than anyone else for that question, and you would have wasted time writing out the bitch of a word. VCAA doesn't expect people to memorise nicotinamide adenine dinucleotide phosphate oxidase. HOWEVER, I personally did do stuff like that in most of my subjects (indirectly of course; I didn't sit down and try to memorise stuff like that) because from my experience, examiners (or at least school teachers) get more lenient on subsequent questions if they realise you're smart :]

qshyrn.. were you the guy that Ian was like "I'm not gonna ask you the question, because you'll know it" at the first Bio lecture :P
I was sitting liek a row behind you :OO:O:O
If it's you :P
I disagree with you, qshyrn - if they say NAME the molecule, they are asking you implicitly to write out the whole name. Although they usually end up accepting both, they always mention it in the assessment report that they wanted students to write it out fully.
True, they will probs accept the NADPH because everyone's gonna write it (given that they wrote about the write acceptor molecule), except my silly friend wrote NADPH+ :P
why is that NADPH+ is wrong?
isnt it accepted as it states charged?

It's NADP+, not NADPH+. It loses the positive charge after being reduced by hydrogen.

NADP+ combines with H + ion and 2 electrons to form NADPH
but i wonder if theyll mark you wrong for NADPH+

Is it also correct if I wrote .. NADH ?

probably not. NADH is the carrier in cellular respiration

Oh no!
