Ocr a biology alevel papers 2009 and before.Watch
The specifications all changed (apart from maths) for exams from 2010 (which is when the A* was introduced for A levels) so the exam codes will all be different prior to that The cash in codes were 4 digits and started with a 7 for A level and a 3 for AS but I can't remember what the unit codes were like.
I'm not sure why I can't find them.
Thanks for the help!!
