I thought it was terrible. It wasn't knowledge based at all and so much elements from the sea. I'm going to really try for the depth but it won't level out this exam to a great extent

Absolutely terrible. The only answer I'm confident about is the 2 mark ozone equations

it was...meh...i thought it was horrible but after discussing some answers im confident i could get...a C? The grade boundaries will be low ish because it's a new spec, don't worry! My chem teacher emailed OCR and they told him they are aware the specimen papers and new spec is hard, and the examiners will make the mark scheme based on answers in the test - i.e. if your answer is obviously correct, even if it isn't on the scheme they will still award marks for it

You work it out from the skeletal formula? Have you not been taught how to name molecules? It was methylpropene.

It was 2-methylpropene

I don't think it's necessary to add the 2 because if the methyl branch was anywhere else it'd be butene

I realises that after the exam, i'd overnamed and put 2-methylprop-1-ene, i dont think they mark you down for overnaming though

Tbh, I thought this exam was harder than the specimen papers they provided us. It was easy to make mistakes in there

Guys how many marks was that last frequency question worth?
I knew what to do but i think i put avogadros constant as 6.02 x 10^-23 and planks constant as 6.63x10^34 - (the wrong way round) do you think ill get atleast one method mark (being extremely optimistic considering i got the formulas mixed up) or should i just forget about it.
