OCR A2 Chains, Rings & Spectroscopy

And the fucntional groups part of the qu....which ones do you mention?

the very part of the last question... a triplet between 1.2 and 1.4 with area 1, though i am not sure the area needed to be specified...

The last few years you had to get about 79/90 to get an A.

But this was the year for which they had a new chief examiner or something, hence you may have noticed the paper was very different (eg much less AS chains and rings and more A2 theoretical content).

My chem teacher, who is a chief examiner and writes the Trends and Patterns A2 paper said that this year the questions and marking should be fairer - and I think it was, and the grade boundaries should be close (UMS should be close to raw marks).

What really annoyed me was they sometimes gave you too much information. For example, in the first question they asked something about naming reagents and conditions for the nitration of benzene, which I answered partly by giving the equation which generates the NO2 electrophile. But then it proceeded to give us the equation anyway, which was strange.

that chem paper was THE hardest paper!! soo much worse than the past papers dont you think? i could not do the NMR at all or that number of electrons in benzene and intermediate....i put 6 and 5. why were there sooo many essay questions and nothing on acyl chlorides?! oh well....its OVER! jus have to wait for the results now.....

The last few years you had to get about 79/90 to get an A.

Hmm, isnt it 72/90 = 80% ? Im sure it is, it cant be as high as 79 outta 90 marks...can it?

well 72 is the UMS marks you get. But how much you need to get an A depends on how well everyone else does as a whole. So if everyone did well on the paper, they increase the grade boundaries, so you may need more than 80% to get an A.
