Hello.

Well, the exams are only a couple of days away for Unit 1 (CBP1-3) and then there's a lovely break before Unit 2 and 3 (CBP4-6, 7) - so, I've created this thread to discuss the topics, potential questions and to help each other (and share answers after the exams of course! ).

Are you ready?

EDIT: CBP7 June 2013 question papers with mark schemes are on page 79, post 1573 by user 'mehjt006.310'

I'm going to revise P4 and 5 after CBP1-3. P5 is really difficult though

I thought that it was alright. They keep recycling the genetic testing questions as 6 markers. Nice easy 3 marker for the carbon cycle and the last question too. I hope that it went alright!

Personally:

C1 - early atmosphere
C2 - nanotechnology
C3 - processes to make limestone, coal and salt OR comparing mining techniques

We've finished them all, but we had to learn some of it at home. I'd recommend getting a book and learning 7's after your 123 exams .

The punnett square (25%) was kind of a maths question, cardiac questions were fine too - anything else mathsy?

The 7s are the hardest and so need the most work, but the grade boundaries are always really low because it's a hard exam (most of the time for C7 you need just over 50% to get an A*) so I wouldn't worry about them too much

There's only been one C7 exam (June) and an A* was 37 and an A was 32 so it isn't bad.
