FP2 Mark Schemes from old P4, P5, P6 and FP1, FP2, FP3 papers (back to June 2002)
Please note that the following pages contain mark schemes for questions from past papers.
The standard of the mark schemes is variable, depending on what we still have – many are scanned, some are handwritten and some are typed.
The questions are available on a separate document, originally sent with this one.
