I agree with this. There were loads of large nested calculation questions where you had to think of a route to the end, whereas in pretty much every single paper in the past, it was just one question made up of 1-mark a), b), c) and so on.

I drew the alkene as a cyclic alkane. Cyclobutane, I think it was.

aah of course thanks

I did this too. I just drew a square though (and didn't write in the carbons) but drew 2 hydrogens coming off each corner, think they'll accept that?

You'd like to think so seeing as they represent cycloalkanes like that in exams .. and it is correct!

i think they wanted a full displayed formula, it was one mark so i doubt they'd be flexible

I did: (85x2.5) + (87x1)
divided all that by 3.5

Got 85 something, I think..
It felt right..

I did the exact same thing; got 85.4.

I think they will allow any multiple of 2.5 and 1 really because you get the same answer for each multiple..

Ahhh, I wrote something like 2.02 then had a last minute panic in my checks and crossed it out .. grrrrrrr. Hopefully I should get a few method marks though :s-smilie:
