CGP
The UK’s No. 1 range for
Grade 9-1 GCSE Science!
Out now at cgpbooks.co.uk
,Beef up your Biological brains with CGP!
Put those electrodes away — if you really want to stimulate your cerebral cortex,
aiming for Grades 8-9 in AQA GCSE Biology will do the trick. It’s a big challenge.
Luckily, CGP is here to help with a book full of questions as tough as any you’ll
face in the real exams. They’ll test your knowledge to the limit, topic by topic —
and there are two mixed practice sections to give your skills an exam-style workout.
Better still, we’ve included step-by-step answers at the back, so it’s easy to mark your
work and find out which topics need most attention ahead of the real exams.
CGP — still the best! J
Our sole aim here at CGP is to produce the highest quality books —
carefully written, immaculately presented and dangerously close to being funny.
Then we work our socks off to get them out to you
— at the cheapest possible prices.
