OCR B F334 - Chemistry of Materials - 19th June 2012

can anyone explain the answer to question 2 e(i) in the June 10 paper f334??
Thankkss

I'm not really sure how to practice for this exam... I just feel like the past papers are a waste of time now :/

I felt the same too - After F335, I just thought that all the revision had gone to waste.
But you can't think like that.

We have to revise properly and do well so we can average a good grade overall.

Good luck

I swear the exam boards are purposely making the papers hard, so that we do bad, don't get into Uni and don't have to pay £9000. The exam boards are jealous that the Unis are talking all the money. It's all fixed.

F335 was actually a joke, though. I cannot believe that's the paper they gave us.

EDIT: How was C3 today?

And you can't discuss C3 until midnight.

Thanks, you too! Going to have to go over the January 2012 paper to see how they ask the questions... and be prepared for the worst

But harder papers mean lower grade boundaries. It's always the exact same number of people getting A's etc...



It was tough not impossible. And you can't discuss C3 until midnight.

Whats the difference between addition and condensation polymerisation?

F335 was actually a joke, though. I cannot believe that's the paper they gave us.

addition is where two monomers are added to form a polymer whereas condensation is where two are added to form a polymer and a small molecule - (H2O) is removed I think!!

Does anyone know where i can find the F334 syllabus? I googled it but can't find it. I use it to judge what i need to revise and what (if anything) i already know

after a flop of an exam that was F335, i need to literally ace this exam to even consider the possibility of getting into medicine. And from Jan 12, my problems aren't actually with the chemical knowledge, its the calculations, so what do you guys recommend? will doing past papers just be a waste of time? the reason i got a B in January was because of that large calculations question (missed an A by 3 marks)
