Title: Statement of Marks Arrived (Anyone else wanna share too?)
Post by: paulsterio on August 12, 2011, 12:44:09 am
I managed to get a 66/72 for Chemistry

MC
-1 on Q8 (Ibuprofen)
-1 on Q18 (IR Question)

SA
-1 on 3)a.
-1 on 5)a. (ii)
-1 on 7)b.
-1 on 7)c.

The dodgy redox question caught me out, but i seriously was 100% sure I balanced it correctly, I think there must have been a misunderstanding about where the numbers went.
If I decide to view my script again, and can somewhat prove that I balanced it correctly, is it possible for me to gain marks there?

Don't know how the hell I got 3)a. wrong!! D:

7)b. and c. were probably the result of some dodgy explanations.

Overall, I think I did well, but VERY VERY annoyed about the short answer, especially since I could have got them all right!!
The two MC questions I'll swallow because I truly did not know the answer!

So, how'd everyone else go?

Hiya

When did you send for it? I just mailed the request yesterday with money order (primitive I know). Any chance of receiving it next week?

Just received mine today and I got 65/72. I dropped 5 marks in the multiple choice which is very frustrating, short answer was pretty good though :)

It gets mailed to you, it should arrive in about a week or so, but if you order it after the results come out, ie. after monday, it can take quite a while, one of my friends says around 2 weeks for him (last year)

Hiya

you probably won't, it'll probably be around two weeks, and oh money order? dont they cost $6, thats like almost the price of the statement itself! :P

Hi! I got 67/72
Does anybody know what sort of study score that translates to, assuming I get approximately the same score for end of years and sacs?
Congrats to Hamdog & paulsterio :)
Title: Re: Statement of Marks Arrived (Anyone else wanna share too?)
Post by: BoredSatan on August 13, 2011, 05:12:39 pm
you're looking at at around 43+ there easily. I would say 45+ but i dont know how well other people have gone.
Title: Re: Statement of Marks Arrived (Anyone else wanna share too?)
Post by: Romperait on August 13, 2011, 06:12:43 pm
That would be 45+ with good sacs this year for sure.
Title: Re: Statement of Marks Arrived (Anyone else wanna share too?)
Post by: taiga on August 13, 2011, 06:28:31 pm
I'd be weary about calling it a 45+ at this stage. Got good marks (72/75) last year for exam 1 (though the cutoff was higher) and performed worse on the second exam (still A+)  and definitely didn't hit that :P

Still another exam to go, so yes you CAN get 45+ definitely but yeah, wouldn't be calling anything definite now because you would probably have to perform a bit better than this sem.

Taiga I read in one of the topics you got a C+ but a derived score? Correct me if I'm wrong?

well "approximately the same score" is a very vague way of saying it
because if the end of year exam was harder than this one, it would mean something different to if the end of year exam was easier! :P

if you were trying to say "approximately the same ranking" that could be a 45+ (which is a 48 scaled mind you :P) but i'd be on the safe side and say expect a 42+
but its good to be optimistic :)

and thanks for the congrats btw (:

What would you classify as a low A+?
Title: Re: Statement of Marks Arrived (Anyone else wanna share too?)
Post by: mattshen on August 14, 2011, 05:43:35 pm
Low A+ = 61.5-63
Low-Med A+ = 64 - 65
Med A+ = 66
Med-High A+ = 67
High A+ = 68 + 
Correct me if Im wrong :)
Title: Re: Statement of Marks Arrived (Anyone else wanna share too?)
Post by: pi on August 14, 2011, 05:44:29 pm
Well, I'd say 61.5-64/72 is 'low', 64.5-68 is 'mid', and 68.5-72 would be 'high'


EDIT: damn you matt :)

does a statement of marks just get mailed to you? And does it only tell you how many marks you got out of 72 or will it tell me which ones I got wrong as well?

Nah A+'s straight through.

Derived happened in 2009. The only weird story I heard was a 46 with a B+ on a derived exam 1. That's about it though.

So I emailed vcaa, and they replied that they have no record in their database of my application or the transaction, so I sent them the bank statement with the payment on it and a copy of my application form, so hopefully it should clear up soon. Dealing with vcaa's inadequacies *sigh*...

Post by: luken93 on August 23, 2011, 07:37:46 pm
So this is my theory, feel free to debate.
 - A+ range is roughly ~10 marks per exam.
 - A+ guarantees you ~38+ depending on how high
 - There is roughly a 4 mark buffer for 50

Hence, if there are 16 marks from 38-49, then you can allocate roughly 0.5 - 1 marks per SS.

These are by no way VCAA supported facts, but it may help with your predictions?

I reiterate though, this is my theory, feel free to debate.

Post by: acinod on August 23, 2011, 07:59:28 pm
I got bored and calculated Thushan's rank in the midyears. Top 4.5% in Physics and top 3.5% in Chemistry. Obviously this isn't accurate only an estimate, or maybe not even an estimate since my concept could be all wrong LOL! *EDIT: Don't worry these percentages are definetely wrong. No way 3.5% of chem students lost 2 marks!

Anyways that 4 mark buffer for 50 is not really correct. My friend lost more than 4 marks in his midyear for Chemistry and he got 50. For other subjects it is even more strange, like my friend in Methods lost 3 marks in both exams combined and got 48 (her SACs were also super high and since she goes MacRob she has a strong cohort and it would've bumped it up)

Really want to find out more about how VCAA works their statistics. Unfortunately we can't get the standard deviation and mean for the seperate calculation for study score. It seems like the standard deviation is 7 and mean is 30 for all subjects but actually every subject is different. I know that Methods usually has a standard deviation of 29.5 and mean of 7.5 but this changes every year.
Title: Re: Statement of Marks Arrived (Anyone else wanna share too?)
Post by: paulsterio on August 23, 2011, 08:13:25 pm
The number of marks you can lose would be dependent upon the difficulty of the exam

If you lose 3 marks on an exam, and that year you were the highest mark, even though you lost 3 marks, you'll get a 50

If you lose 2 marks, but a lot of people lost only 1 or 2 marks, you might end up with a 48, even though you lost less marks

I asked the same question with my 64/72 and a few people had doubts but said that if I only dropped about 1-2marks on the end of year exam I might stand a chance :S

Yep, and you'd need a very very high A+ in SACs and exam 2. More likely is 40-42 high mid-high A+s.

This, only I lost one more mark on MC Q15... *facepalm*
But of course I'm happy with 69

nice work funky!

I got bored and calculated Thushan's rank in the midyears. Top 4.5% in Physics and top 3.5% in Chemistry. Obviously this isn't accurate only an estimate, or maybe not even an estimate since my concept could be all wrong LOL! *EDIT: Don't worry these percentages are definetely wrong. No way 3.5% of chem students lost 2 marks!

Anyways that 4 mark buffer for 50 is not really correct. My friend lost more than 4 marks in his midyear for Chemistry and he got 50. For other subjects it is even more strange, like my friend in Methods lost 3 marks in both exams combined and got 48 (her SACs were also super high and since she goes MacRob she has a strong cohort and it would've bumped it up)

Really want to find out more about how VCAA works their statistics. Unfortunately we can't get the standard deviation and mean for the seperate calculation for study score. It seems like the standard deviation is 7 and mean is 30 for all subjects but actually every subject is different. I know that Methods usually has a standard deviation of 29.5 and mean of 7.5 but this changes every year.

ahaha u used the z-score? not the best here; scores are not actually normally distributed in reality.

lol i think so, i used normCdf([score],∞,[mean],[standard deviation])x100%. So for Chemistry I plugged into my CAS: normCdf(178,∞,102.3,41)*100%=3.24313%. Any idea how to find out the real statistics though? I've been searching for ages :(

Is it possible to calculate anything if we know that for Chemistry Mid-Years - the mean is 102.3, standard deviation is 41 and our score?

real stats? they don't release :(

So there is no reliable way of estimating one's study score then?

Post by: paulsterio on August 24, 2011, 12:15:18 am
you cant estimate it anyway, because as we all know, the difficulty of the exams vary WILDLY from year to year, so even the Z-Scores won't be of much use (if you're using last years values for example)

he would have had to get basically 100% on the end of year exam, and that exam had to be a hard exam :)

hmm, i also have a friend in macrob who lost three marks in the second exam for methods (having got 100/100 for SACs and 40/40 for exam 1) - and also got 48. we might be talking about the same person though?

I really don't know what the buffer is for chem; it varies from year to year I daresay, depending on how hard the exam is.

like we cant deny that there are A LOT of people who are doing methods that really shouldn't be
say if my school gave a sac of the difficulty of say 2010's exam 2, im pretty sure that only about 3-4 people in my class would even be able to get a decent (85%+) mark

I think my SACs are above VCAA standard, but I'd need other opinions to make sure. Our average SAC scores are usually lower than other schools, however we always do well in exams as a cohort (ie. much better than SACs percentage-wise), therefore I'd assume that our SACs are harder than exams.

that's better, because i guess with melbourne high, they can afford to make it harder, because what schools want is to end up with sort of a normal dist. of sac scores, it kinda helps everyone, with melbourne high, you probably have a much stronger cohort than other schools, so your mean would be higher, meaning that they have to make sacs harder to counter that, otherwise everyone would get 100% or close to

but with my school, i dont think our cohort is as strong as MHS's, therefore, if our sacs were as hard as yours, we'd probably have a lot of people getting like 50% whatnot, even though we get good separation at the top...that's why they make it easier, so that everyone kinda "does well" which evens everything out a lot more

if you get what i say, it makes sense in my head :P

My school's methods and spesh sacs are generally harder than vcaa exams; same goes for chem. Some of my spesh sacs have been really difficult, with no one finishing or getting full marks. For one, the highest mark was 17/20, and this is out of a cohort including ~10 45+ scores in methods last year.

our sacs are generally very straightforward, although I would say that they are just above VCAA standard (for both methods and spesh). however, my school has a reputation for setting an impossibly hard sac at the most unexpected moments...my last spesh sac was riduclously hard - whereas all the other ones were quite straightforward

i thought that "down here it's every man for himself" :P YES I KNOW MY QUOTES ;)

but seriously though, they have to be stingy with the marking, cause with a sac that easy, to do in 2hr 40min...they cant have everyone doing well

diverging off the topic, but theres this guy at my school, he's a PhD in mathematics and he sets the most impossibly hard physics sacs, and he's the master of taking marks off

one of his questions (on the sound practical sac) was like what would the sound intensity level in decibels be if we doubled the distance
somehow i managed to read that as half the distance, and i went through and did the correct calculations and even wrote the right formula and i got 0

Yeh, him and Yarussky think Australia's maths standard is crap, so they make up their own standard. As an example, our next sac will have a part where we need to use hyperbolic trig functions in various DE questions (usually 8-10 mark qs) with no CAS :( And that is just one part :(

It's fun maths though, except when we get our marks back
