Introduction:
These OCR specifications lead to qualifications at Advanced Subsidiary and A-level in Human Biology. Both Advanced Subsidiary and A2 combined constitute the full A-level specification. 

Prerequisite:
Students applying for this course must possess ‘B’ grades overall in the Double Science Award, or ‘B’ in the Biology Separate Science Award.

Course Content:
Both AS and A2 courses consist of three units all of which are compulsory. The first two units are assessed by written examination in either January or June, and the third includes assessment of practical skills which is internally assessed. 

The units for AS Human Biology are:
