Who knows, last year for exam 2 it was 123/160 while it was like 146/160 for a few years before that


I hope they make it hard this year, the lower the A+ cutoff the better.



I actually want a challenging exam 1 for once

Same here! :D

Before, I hated Methods, but now I actually like it. Hope we get a hard Exam 1 and 2. :D

WOW! Thank you very much for posting that.

EDIT: The A+ cutoff has never been between 150-160 for Exam 2 - Lowest was 144. And in fact, it was very low last year as well. Hopefully the class of 2013 breaks the record. :P

I know the highest for Exam 2 for Specialist was 147 last year.

Interesting how the Average A+ Cutoff for Spesh is significantly higher than Methods.

Possibly due to less students? ???
Title: Re: Whats the normal A+ cutoff?
Post by: Damoz.G on November 03, 2013, 10:16:49 pm
Yep and the quality of students is a lot higher

Hence why if you get 40 for spesh that's better than getting 50 for methods.
(40 scaled to 51 last year)

Good point - Forgot about the Scaling bit. :P

WOW! If you get 50 (Raw) in Methods, it doesn't Scale up?  :o

Spesh exams are also typically easier - having learnt the content - than Methods exams.

WOW! If you get 50 (Raw) in Methods, it doesn't Scale up?  :o
Subjects only scale about 50 if the mean plus twice the standard deviation of their scaled distribution (what you see on the scaling report) is 50 or above. Assuming a standard deviation of seven, the mean of all the scaled scores of all methods students in their other subjects would need to be 36 - it's close, but not quite there. Keep in mind five is added to the mean scaled score of languages.

Ohh okay. Fair enough. That makes sense.

Thanks. :)

What SS would I get if I'm ranked 3rd with 90% SACS and get A+ on both exams but 1st and 2nd rank get C?

1st and 2nd get a C? Hmm... you would probably get a 49. :)

WOW! Really!? I was told that if the students ranked infront of you end up getting higher than them, then it will bring your study score down?
Title: Re: Whats the normal A+ cutoff?
Post by: leflyi on November 04, 2013, 02:12:17 pm
It's better for your class to do well as a whole that well individually. You wouldn't get 49 I don't think, still it would be high, but your mark would be affected.
Title: Re: Whats the normal A+ cutoff?
Post by: Damoz.G on November 04, 2013, 02:18:01 pm
Well actually yeah. It might depend on indicative grades and GAT Scores as well.

Erm...we haven't been given enough information yet. For all we know, the A+ in the exams might be borderline A+. In which case you wouldn't make a 40 with three low A+'s. Then, as those in front of you apparently fail, your SAC grade will be affected.

Best to aim for 100% in the exam, stuff the cutoff and possible grades.

It's only a rough estimate. :)

be affected in a good way or bad way?

I think in a good way, but its a really complicated process that I don't even think VCAA knows. :P

Just do the best you can on the Exams, and let VCAA worry about the rest. :)

A specific percentage of students get A+ (usually about 9-10%).

Basically, A+ cuts for spesh exams are high these days coz they make the exams extremely easy.

It's actually not 1st or 2nd rank's exam grades that matter. You just need ANY OTHER two people to smash the exams to ensure your SAC scores don't drop.

How about abnormal results? Say the people ranked higher than you generally get higher scores, but the guy ranked above you screws up big time. Will that affect my results?
Title: Re: Whats the normal A+ cutoff?
Post by: thushan on November 05, 2013, 01:00:25 pm
Maybe a little, if there isn't another person who is ranked below you in SACs who does better than you in the exam.
Title: Re: Whats the normal A+ cutoff?
Post by: lzxnl on November 05, 2013, 02:40:48 pm
Isn't that sort of funny though, that you need someone below you in SACs to beat you in the exam for your marks not to be affected?

That's not true, and an oversimplification of statistical moderation.
