Possibility of Study Score Calculator?

<< < (7/9) > >>

reg:
I'm 99% sure VCAA are dirty scammers.

I've been writing this calculator, and we can see valid results for a 30 score:


But trying for a 45 score:


More than 100% for GA1 and GA2? What?

Assumption 1: I was under the impression that, for example, a median in each GA would contribute equally EDIT: proportionally, not equally, equitably to a median study score (where GA1 = 50, GA2 = 50, GA3 = 400 marks) .......

Assumption 2: Pr(STUDY > 45) = 1 - 0.983938. Hence, taking the inverse of each GA for 0.983938 should give the required score for each GA?

Or have I got it wrong?  ... this is all based off exact data provided by VCAA about 2006 ..

It's not a coding error either, my calculator agrees with me.

F U VCAA.

Funny. We both get the same results.

I couldn't write jack for DOS programs.

If you look at the proportions, the distributions are NOT normally distributed. That's why it must all be manually inputted.

I'm sure you'll find the French Exam scores are a little too high as well. As long as all your code is correct, I'm sure that's the issue. That's why assumptions are no good.

To be honest, I suspect VCAA do their own twiddling in the meantime. I'm certain that even with crap exam scores, I can still do well because I suspect they take your OTHER studies into account when moderating your scores.

i.e. I get average 45 in all my subs except a 30 in methods.
VCAA inexplicably lift my methods score to 33. Why? Because of the moderating process.

They don't tell you everything, though... So yes, it is difficult. That's what real data can help you with.

EDIT: I might do some more research into the grading process undertaken by VCAA. This looks like an interesting side project.

Meh, as coblin said, the lack of transperancy in the system is a bad thing...

Here's my code anyway. Written in C++, for gnu gcc. Using boost::regex
study_calc.cpp - http://pastebin.com/f4755d394
study_calc.h - http://pastebin.com/f4f938292

Binary + sources: http://download.yousendit.com/0D05BBE02DCF3328

Only one set of grade data included (for French), but it can be generated by getting a PDF scaling report from VCAA, saving it as .txt with Foxit PDF Reader, and my program will parse the rest.

My thoughts: this is bloody stupid. vcaa says study's are normally distributed mu = 30 sd = 7, no?

That is pretty hardcore

just wait for your SCORE! either way you get the same score wether you spent 50 years making the study calculator or you didnt and enjoyed life!
