Exam stats + grades

[omgwtf123]

shit soz for posting it twice >.<

[thushan]

Not the graph, read the "score range" below grades

Ahaha it depends on the chief examiner. For instance, the chief examiner for bio is very very very very harsh. Chief examiner for chem was quite the opposite. In fact, chief examiner for chem rubbished the IR multi-choice qn, saying it was a ridiculous qn and he never taught his class that, nor will he ever. But because it was a multi-choice question, the exam writers have the final say.

A+ cut off is 123 marks out of 144. percentage it


EDIT: Whoops there is a second page to this. Didn't see it.

if they scrap the IR questions and some of the MC choices which were a bit ambiguious.. i may be able to scrap an A+

[funkyducky]

I wish they would scrap the IR question, it was the kind of thing that you'd only know if you'd read the heinemann textbook religiously, most people who got it right would've guessed, which kind of defeats the purpose of the exam, which is to evaluate our knowledge and comprehension,  not to check whether we had memorised a somewhat arbitrary fact that not many teachers taught their students.

Edit: wow that's a really long sentence

And if thushan had no idea, then clearly it was way out of the scope! It should've followed the NMR where you don't need to know how it works, just be able to interpret the results.

Wait, what is this IR question your all talking about ?
Was it in the MC?

[b^3]

Just remember guys, there is no point mulling over something you can't change. Time to ace unit 4!
I'm so close to finishing it's not funny, but I have 4 sacs to think about in the next 4 school days

Yeah, one of the last MC Qs. It asked which factor contributes most to the position of a bond's wavenumber...

[Dr.Lecter]

for the 'major component of biofuels' question, was the answer definitely methylester?

Just want to say, I love you Chemistry Examiners, you people are so kind to us. Thankyou for not hating on us students.

A+ for 85% is generous

They just pick the mark that gives a statistical distribution with ~10% of students scoring A+. Don't thank the examiners, thank everyone who did worse than you on the exam

Edit: In fact, only 9% of students got A+, meaning the examiners erred on the less generous side.

Hahaha

How did you go according to the suggested funky?

[cltf]

sorry, but this might be a noobish question , but how do u read the graph and know A+ cut-off is roughly 85%?

Note the Mark range, eg. A+ was 123-144, the exam was out of 72. So if you half it, its 61.5 - 72 which is 85.42%
