A+!!!!! fuck u asian geniuses!!!!! ;D
-
Got an A YEYYYYYYYYYYY! Exaclty what I was expecting.
-
B+ :-\ I was hoping for an A, but I was expecting what I got so it's not too bad.
-
sigh, B+
fucking devastated.. wanted atleast an A
-
I got an A. Really happy but i was hoping for an A+.
Is it still possible to get ~43 with an A?
-
A+
FUARK YEAH
-
B+ :(
assuming it was high (if its a low B+ omg.)
is a 40 possible at all?
-
A+ YESS! not looking forward to the discussion with my friends....
-
Got an A. want a 35 for chem, so i guess im on track. 8)
-
I got an A. Really happy but i was hoping for an A+.
Is it still possible to get ~43 with an A?
definitely. I got A in accounting and I got 43. Plus chemistry scales UP alot more than accounting. keep working hard.
I got an A by the way.. :)
-
W0000000T got an A, except i think i was only a mark or two off an A+!
B+ :(
assuming it was high (if its a low B+ omg.)
is a 40 possible at all?
From what i've heard it's still possible.
-
is this real life?
-
A+
Don't know how, but yay!
-
B+ :(
-
B+ was expecting it anyway since i messed up the exam
-
A+ :)
-
B!!!! fuging rapped!! was expecting a C!!!!!!!!!!!!!!!!!!!!!
-
I got a b+ i am not that happy however i am only in year 11
-
A. Even if I had gotten an A+; I would still have been pissed off at the exam.
-
I got an A. I'm very happy, cause I thought my maximum score was B. :) But is it possible to get above 40 with A? :< Last year, I got A+ for everything in history and ended up with 42, which is low 40s. So does that mean I will get below 40 if I have an A? :<
-
A+ in Chemistry
Apparently the IR MC Question got taken out, does anyone know if this is true?
-
what would an a a+ a+ get?
and what would a (b a+ a+) get?
assuming all are of highest possible letter grade in that category.
-
A+ :D
@Thelimz -> if ur As were highest possible As and both ur A+s were 100%, then i'd say 43?
The IR question was rubbished by all the assessors, so the Chief Examiner took it back to the exam writers (it's the writers' decision for MC qns) saying it was a cruddy qn. Exam writers have the final say.
Not sure what the writers' decision was though.
-
Got a B, never been so shattered!
With an A on SAC's, what do I need for exam 2 to get a 35-36 raw...if thats even possible
-
ouch man! but you can bounce back! i think a mid A+ would do the trick
-
OH MY GOD. I THOUGHT I WAS GONNA GET A B.
WAS HOPING FOR B+
GOT AN A
;D
-
A. Even if I had gotten an A+; I would still have been pissed off at the exam.
Yeh me too, did so many stupid mistakes, there wasn't really too much on the exam that was hard. I predicted both my marks for Chem [A] and Physics [A+] :)
-
No idea how I got an A+, but I did.
Definitely gonna have to get the SoM to see - I bet I was on the border of A->A+ region :S
-
Yeh I reckon I was a high A, got that feeling that I "missed it by that much".

hmmm, well i did go and research up that IR stuff, and apparently all of the options would have made a difference, the question was badly worded anyway
cause if the answer IS mass, then how does it explain why C-C and C=C would have different IR absorptions, if you get what im trying to say
but yeahh, i hope they do take that question out (just cause i know i got it wrong anyway ;)) :P
btw @thushan, congrats on the 50's ;)
-
Yeah...
EDIT: whoops, didnt read whole post, thanks paul!!

I hope i'm around the border for A+ as well. My exam predictions failed though. Thought i'd get ~B for physics and A+ for chem :-\

I can just see us having a similar convosation at the end of the year with Thushan with another 3 or 4 50's. Do it for Atar Notes Thushan!

i just love how you can get like 5 49's and people are just like, yeahh he's smart
and you get like a couple of 50's and everyones like wow, youre god!
but yeah, do it for atar notes ;)
-
A+ :D
-
Was seriously expecting like a B+ after all my friends who were expecting A+ got A's or lower..
Some how got an A+.. seriously do NOT know how.. must have got like 61.5 exact and scraped it.

Me too. Haven't done anything since I got home. Oh NOOOO! I've lost 4 hrs of work. Must go and finish the last 3 pages of the spec book. *runs*

By studying you mean commenting on someone in particular's fb status. Hehe
I got A+ :D

just wing it all ;)

B+
Still possible to get low 40's raw?
-
A+
Pleased :)
-
ok... so i bombed out chem exam... B.... wat's the highest ss i can achieve?
-

I have heard of someone with a 38 raw (scaled 41?) :)
Not too bad after scaling :)
-
wow nice :D, raises my hopes now
-
The two questions I messed up on were the two questions that got taken out.
YEAH!
-
The two questions I messed up on were the two questions that got taken out.
YEAH!
What questions got taken out? I know the dodgy redox equation did, what was the other one?
-
The IR one in MC? Whooooo!!!!!
-
Absolutely devastated.... B+
40 gone? ='(
-
The IR one in MC? Whooooo!!!!!
AWESOME! I GOT IT WRONG TOO!
-

YEAH!
Do you know this for a fact? Sorry to question it, but it seems pretty strange that they did...
-
A+ in Chemistry
Apparently the IR MC Question got taken out, does anyone know if this is true?
No. My teacher is the chief assessor, he said it was a legitimate question

Exactly what I heard as well.
-
I got an A, not disappointed as such but definately considering the possible what ifs
-
Was expecting a B, C+ worse case, ended up with a C, fucking shattered, honestly i don't even know how i could have done so bad, i'm so disappointed, i really want to look at my exam and saw where it all went, never thought i would have done so bad. Assuming that i can do damn good on the next exam B+ (min) and i'm doing damn good on my SACs, what can i expect for a SS? Ty Guys
-
Got a B+, which was what I was expecting since I made so many crap mistakes.

Aw, that sort of sucks then. :( I was pretty excited.
-
The dodgy redox one wasn't that bad, i think if you just looked at it for a second, it would have made sense, its not an actual "error"
but im still sticking with that IR MC question, cause no one can seem to explain that if its mass only, then why is C-C and C=C different, arent they the same mass?
i also found some info that states electronegativity and size (ie. radius) also plays a part, ill post it up when i manage to find it, its from the UCLA (so yes its credible)

Yeah i chose electronegativity based on the double bond theory. Surely they wouldve scrapped a question, cos if you didnt have heinemen text book, you wouldn't have known.
-
Really? Damn. Hmm. I heard from my teacher (an assessor) that jackson's teacher (Chief Examiner) said that "he didn't teach his class that (the IR mass thingy) and he will continue to not teach his class that." Maybe I heard wrong.
Btw - two things that affect wavenumber are mass and bond length. Reason C-C and C=C are different is because one has a shorter bond-length than the other.
Whilst mass is the correct answer, I also stand by "atomic radius" as another possible answer as this is highly linked with bond-length, which could explain the discrepancy between the C-C and O-O bonds (in relation to the data at large, check data book).
Electronegativity may have a slight impact in that the bond may be stronger due to the polarisation and dipole formation, and stronger bonds are shorter.

good point there
well, it makes sense for it to be scrapped because chemistry has always been a subject about skills and applications, rather than stuff like this, which is rote memorisation, this doesnt require thinking, this requires memorisation of that page of the heinemann text book, and either way, i havent managed to find this information in any other textbook and also, without someone telling you the answer (ie the textbook) you cant exactly derive it =.=
but im not sure, i ordered my statement last week, so it should arrive early (ie this week) that should put an end to this
ill let you guys know

Its mass of the atoms attached to it?
I was lucky to have it in my notes :)
-
I think it would've been fair game if you could actually find the answer, but the fact that there was a discrepancy (despite it saying "best" supports) made it extremely difficult to get the answer.
Ah well, hopefully I get my SoM ASAP and I can stop these rumours from occuring!

ohh (: well congrats on having it in your notes tashi :P
omg, you make me feel bad that i want this question taken out, cause that would disadvantage people who got the answer :P
gee thanks :P :P
but i still think luken93 points out a good point that there was a discrepency

yeah thushan dw man, i bet the percentage of people who got that right was like 1%. to be honest. Ull get 50 :P

one of my friends was randomly reading the textbook before the exam, and he just happened to read the sentence in the heinemann book that says it was mass, dodgy

Wish I could say that, i dropped another careless mark ahahah
-
Wish I could say that, i dropped another careless mark ahahah
well they do say its the careless errors not the knowledge that separates the 48's to 49's to 50's
haha, good luck though, hope you get that 50 ;)
-
A+ :)
-
Saw the stats today, the IR question and the redox Q were definitely both counted. Unbelievably, 20% got the IR question right - good guess :P
As for the Ibuprofen though, only 6% got it correct in the state hahahaha

Where did you see these stats? And hey, some of us didn't guess lol! I had no idea on the ibuprofen one.
-
Screwed up bad for chem, got a C+, i hope i do better for the end of year... Is it still possible to get 35 SS?

i also found some info that states electronegativity and size (ie. radius) also plays a part, ill post it up when i manage to find it, its from the UCLA (so yes its credible)
its dependant upon BOTH mass, and bond strength, if you look at your heinemann book

It is definitely the mass, end discussion now, nothing you say or do is going to change it unfortunately...
-
Indeed. I know stats for my 3/4. One Q was such a bitch only 15% got (erm..guessed) it.
2010: VCAA fucked up all exams?
2011: VCAA fucked up u3 MCQs.
2012: VCAA ......
-
Got an A+. YEEAAAAHHH BUDDDDYYY
-
A+ somehow... Either they gave me consequential marks for Q4a) or they accepted my response for Q4b) even when I said that the results would not be the same. Not complaining :)
-
I cried, I got a C+.... BUTTT the most worrying part, is that C+ is the highest mark in the whole grade at my school... WHAT SHOULD I DO?? I WANT TO GET AT LEAST 30 :(

In terms of probability, if everyone guessed, 25% would've gotten it right, so yeah, less than that means there was a lean towards one of the other answers, probably atomic radius,

-
A+ biiiiiiiiiiiiiiiiiitccccccheeeeeessssssssssssssss
but yeh, i'm pretty happy.
-
A+ :D Good luck with U4, let's kill it :)
-
A, higher than I expected :)
-
A+ :)
Good luck to everyone for the Unit 4 exam!
-
I got an A. Really happy but i was hoping for an A+.
Is it still possible to get ~43 with an A?
I got 43 with two A+s, so I guess you'd have to nearly get perfect next exam, plus top of your class for SACs to still get 43 or above.
-
See here for official solutions, only posted MC but if you want any answers to the SA, let me know and I'll try and remember what I wrote :)
Statement of Marks!
-
Expecting a B, got an A+ :D
