Here is the Mark scheme for June 2013 - Sorry if it's late guys, I was going back home from the library
Also, Can anyone help me with bonding?
Do we all agree that it is by far the trickiest topic in f321 because of how wide it is and the confusion of the bond angles/lone pairs/ symettrical molecules? I just think that OCR will take advantage of this particular gap in people's knowledge and make sure they test this thoroughly - this year all exam boards seem to be set out to trip candidates up anyway, so I reckon this is what will be done in the exam tomorrow.
I mean in my WJEC biology BY1, They asked a question from The next unit that wasnt even on the spec. Anyway.
