Hello.
I've got the OCR Gateway B: Biology B4-B5-B6 exam tomorrow and I have been revising via Collins GCSE Biology revision guide which I have found very useful. I have only just found my CGP Biology revision guide and comparing the two guides; CGP has much more detail which I'd never cover in time.
So my question is: Is not revising from the CGP Biology revision guide going to cost me (as I'm aiming for the A/A*) or does the Collins Biology revision guide cover everything I need to know?
Thanks.
