This year for AS I failed my Bio exam (educas board) and want advice on what I need to do to get an A/B in A2. Btw I did not revise for this exam & so I believe I can achieve a really good grade if I start revising from the start. Just want some advice on what to tell the teacher to let me on & this AS grade does not contribute to the A level grade meaning my real exams are at the end of next yr
