OCR A Chemistry F324 Rings, Polymers and Analysis Thu 26 Jan 2012

Im hoping the grade boundaries will be quite low to make up for my silly mistakes

A couple of times I have seen that 100% UMS is around the 53-56 range.

I really dont think so.
If you check the ocr grade boundies 100% is always full marks.
(please prove me wrong xD)

Lol, no 44 is an A, difference between an A and a B is 5 marks. 44 raw marks =80%ums. 44+5+5=54 or 80% + 10% +10%=100ums. So any mark between 54 and 60 is full ums

Isn't this paper out of 90ums? At least that is what it was last year

They are nucleophiles I swear it!

well $CN^-$ is the nucleophile i think

But if you look at the max mark column it says Raw: 60 UMS: 90
Unless im going crazy and just reading it wrong.

I know what you mean, I knew all the content but still kept losing silly marks. My marks have been 49, 53 and recently 56. I usually misread the question and lose marks or sometimes the stretch and challenge questions I lose marks

How are you lot revising btw?

I've already done all the past papers for this specification, so not really sure on what to do next.

My marks were fairly average for the paper (around 40 give or take)

What do you suggest - quoting you because of the high marks your getting lool

Yeah, 60 marks will get you 90 ums but so will 54. I can't really explain it well but trust me when I say 56 marks or more will get you 90ums. Theres a 5 mark gap between each grade i.e 39=63 ums(B) 44=72 ums (A) 49=81ums (A*) and then by deducing you can work out 54=100 ums.

You explained it well!
I like OCR a lot more now.

Haha, no problem. Firstly make sure you know every single definition, they are usually easy marks. Memorise the mark scheme answers for questions such as " describe the bonding in benzene" as specific points are usually required for the marks. Questions such as "suggest an impurity for the reaction" are common because candidates find these questions hard.
Check through examiners reports and get an idea of which questions the examiners say that candidates found hard, there's a good chance they'll repeat these questions.
Always read the full question so like me you don't make silly mistakes.
Old spec papers may help but the format of the exams is different so don't get too hooked on them.
Because OCR are moving towards "application of science" questions you have to prepare for these. They can dress these questions up, by putting lots of different functional groups or bonds or complex polymers but at the end of they day they can only ask what you know. So try to simplify these difficult looking questions.

Sorry I can't be any more specific.
Hope it helps anyway

Nah thanks a lot that's great advice.

I wasn't too sure whether to start on the old spec papers, but I think my time will be better spent going over the past papers/ stretch and challenge/ reports.

Thanks!

How long did it take you in terms of revision to get that 56/60 mark, was it a first attempt or what? (bit nosy )

Good luck guys with this paper!
Dont stress, read the question properly, make sure your not just using that OCR book for your revision- its way too simplified. Memorise mark schemes and analyse the way they want you to answer the questions.. and ofcourse learn your content inside out.
Feel free to ask any questions etc x
