Summary
CCEA Biology AS Unit 2 Full Notes For Every Topic *Revised Specification*
These are the new specification notes for the Biology AS Unit 2, I achieved full UMS in the exam and an A overall. They are very condensed but still have all the information required for the unit making them perfect for revision purposes.

As a student doing the new revised spec - especially on CCEA where there are little resources available, I know how hard it was to make good revision notes which is why I decided to release mine.
