Title: What do u think u'll get?
Post by: hifer on November 12, 2007, 03:22:13 pm: So how did everyone think they went for both exam 1 + exam 2? Total is 120..
Title: What do u think u'll get?
Post by: Toothpaste on November 12, 2007, 03:28:25 pm: I'd say 100+. So I picked the second option, in case I overestimate. LOL.

I liked exam 2.. alot. :D

Post by: Matt89 on November 12, 2007, 03:46:35 pm: I only lost one mark in Exam 1, but i'm not too sure how well i did on Exam 2. Dropping 9 marks would be surprising, so i think i will get above 110 (barely)

Post by: JL_91 on November 12, 2007, 04:09:08 pm: i do CAS, also got 39 on the first one...but i'm VERY pessimistic about how i did today, so picked the 90-100 range :(
Title: What do u think u'll get?
Post by: Eriny on November 12, 2007, 04:37:29 pm: I think about 90: 30 on exam 1, 60 on exam 2. Although it's entirely probable that I lost more than 20 marks on exam 2.
Title: What do u think u'll get?
Post by: bilgia on November 12, 2007, 04:55:09 pm: im thinking lost 1 from exam 1 and prolly 6 from exam 2..i wonder what study score is possible..
Title: What do u think u'll get?
Post by: Defiler on November 12, 2007, 04:58:17 pm: 80-90 perhaps? Who knows.
Title: What do u think u'll get?
Post by: vce_2007 on November 12, 2007, 05:41:17 pm: i just want a 38+ grrr but b/c of exam 1 i dont think its gonna happen

Title: What do u think u'll get?
Post by: kido_1 on November 12, 2007, 06:09:29 pm: Range:

Hoping for the best but expecting the worse~ Forever Young~ i want to be... XD

i say i lost 5-10marks( im sure some stupid mistake would haunt me. I just can't pinpoint what it is)

Post by: dashkenny on November 12, 2007, 08:07:14 pm: YES 50 for me ! :)
Title: What do u think u'll get?
Post by: azhtey on November 12, 2007, 09:33:08 pm: Below 60 lol
Title: What do u think u'll get?
Post by: 2happy on November 12, 2007, 10:27:46 pm: what score for exam 2 would you likely to get if u did all the "method marks" and got most qstns; but didnt get the 'correct' answer for 5-7 qstns; i.e. wrote 14.5 instead of 14.7 ???
Title: What do u think u'll get?
Post by: asa.hoshi on November 13, 2007, 12:25:02 am: what do you think the A+ borderline would be. im sure it won't be like last year's. 73.5 out of 80... what a joke... lol

68/80?
Title: What do u think u'll get?
Post by: enwiabe on November 13, 2007, 01:56:04 am: My tip is 70/80 :)
Title: What do u think u'll get?
Post by: kido_1 on November 13, 2007, 05:08:33 am: See how they say:
Exam 1= 22%
Exam 2= 44%
SACS = 34%

How do these results come out to be a total.Do they just add 160, 80 and 100?
Title: What do u think u'll get?
Post by: asa.hoshi on November 13, 2007, 10:27:08 am: separately.
for each result, VCAA calculates your standardized score.
i.e. just say you scored 22/40 for exam 1, and the median was like 21, your z-score (standardized score) will be just above zero. (we learnt this in methods). just assume your z score for exam 1 was 0.0112845
and then with the z-score they multiple it with the % it is worth
so 0.0132845 X 22%
(called weighting X standardised score)
They do that for all the components of the study score.
Add it up altogether to give your weighted total.
and just say you end up with something like 1.051251... is equivalent to a 36 study score. get me?

if FSN found it hard. i think the whole state found it difficult. i reckon mid-high 60s for an A+ for exam 2 methods.

Chemistry Unit 3 certainly wasn't like that though...

true. but that's chemistry. haha
Title: What do u think u'll get?
Post by: Collin Li on November 13, 2007, 10:42:48 am: Haha. Hmm... I wonder if FSN actually is the upper end. It certainly seems like it's going to be ENTER > 70, or something, but a group like ENTER > 90 (MHS, for example) would be much better at evaluating A+ cut-offs.

so true. i asked a couple of mates from MHS and they told me that the methods exam was hard. haha. can anyone else confirm this?

Post by: div123 on November 13, 2007, 11:01:48 am: yeah mhs kids did find it on the tougher side...like the mid range kids im talking about. As fort eh upper ranges, they would have lost about 2-3, i knwo our methods prize winner (i.e best mark in sacs all year) dropped at least 2. So u can guage for yourself.

so its fair to say that you can afford to drop about 2 marks on exam 2 and 1 mark on exam 1 to get a study score of 48+ then rite?
Title: What do u think u'll get?
Post by: div123 on November 13, 2007, 11:09:23 am: no idea, but all im saying is that some mhs kids found it hard as well (i.e induced stupid errors). However, while mhs is above average as a cohort, u have freaks from everywhere. Like u can have peoplpe who will get 50 no matter what hardness from non-mhs schools. so while its an indicator, its not definative.
Title: What do u think u'll get?
Post by: golids on November 13, 2007, 02:55:30 pm: 110+ i'm guessing

don't think i dropped a mark on exam 1 except possibly that anti diff q

exam 2 i know i stuffed up 2 q which were worth 5 marks total IIRC

ah well, at least no more methods

btw what raw ss would i be looking at cheers in advance
Title: What do u think u'll get?
Post by: kido_1 on November 13, 2007, 03:52:57 pm: Probably 45

Man I am so pissed I put probability of p=3.414. #$#^$%$^%#$(Pr always <1).

Thanks mate

Now I get it. (Btw, do you know what sort of standardised score you would need to get to get a 45-50?)

well you can kinda work it out cant you? z = (x - u)/sd (the equation we learnt in methods for standardised score)
