A2 Biology F215- Topics covered on previous exams and specimen (before June 2011)

A list of topics which have been on previous exams and the specimen, and also topics which have not come up at all. Every few years the examiners have to ask a question on each topic on the syllabus, therefore if something has not come up yet there is a strong chance it could do this time round. This list will just help in focusing revision.
