That NMR question was tricky in my opinion. I did that as a mock and felt exhausted :P

Overall it was OK

NMR splitting pattern does my head in all the time :frown:

The question on chiral center's also looks weird :/

This paper is 100% synoptic, so there's literally anything they can chuck at us. I'm terrified! :colondollar:

The chiral one is odd because it starts easily enough but then throws in a curve ball using cis/trans in a context where it is not about a double bond. You have to think in terms of groups and 3D positioning.

Hmm that makes more sense. Cheers! :smile:

HERE IS F335 Jan 2013

Sorry for the ghetto photo scan and the occasional wrong answers and the awful handwriting! Corrections are blue ink, I think I corrected most of the questions! Hope this helps team! (I've hopefully got better at chemistry since doing this paper a few weeks ago).

PS. Grade boundary for an A is 82/120

I haven't missed one, there is actually a page number error in the paper. If you add up the marks it still works out! Good spot though, I hadn't noticed! :smile:

We did that mock. Thought my mark (around 75 ish?) was terrible, but turns out the grade boundary for an A is 82 you say? Wow, hahaha. Fills me with a little more confidence.

Yea, gotta remember that these papers are hard as nails for everybody and the grade boundaries reflect that. I actually made a mistake with 82, the grade boundaries are as follows:

A 84
B 75
C 67
D 59
E 51

Ah fair play. This is arguably my most important exam, so I'm bricking it. Haven't properly started revising for it yet, but we'll see how it goes. I don't usually start revising until ~1.5 weeks before/2 weeks before first exams.

I have just been doing light revision since easter, a past paper ever couple of days. First exam isnt for another 5 weeks or so, so plenty of time!

Does anyone have any predictions on what is most likely to come up based on what has been in the exams for the past few years??
I saw a table showing what had come up recently for f334 and it was very accurate in predicting what is most likely to appear!!

Everything will come up, usually the F334 papers have 90% of the stuff in

Ooh, any chance you could send the link?

can someone explain why this paper which is mainly synoptic, is before F334? it makes no sense to me and just makes my revision structure harder to keep on top of.
