Can you retake a different A level compared to those at AS and A2?

Hello,
I've done my a level biology exams this year and it's not look too great. Is it possible to take a gap year and pick up another subject for instance philosophy and ethics or politics? I really don't want to retake biology, no matter how hard I try the results are never in my favour. I'm willing to retake both AS and A2 for this subject and if I don't get atleast As in my other subjects (Psychology and English literature) I may retake those as well. Thank you !

Yes, you can take a different subject in a gap year. It's up to you how you do this - you might go back to college for lessons, study through distance learning, or study at home independently. You would need to arrange to take your exams at an exam centre - many people use their previous school/college for this. You will be charged.

Thank you. Is it possible to do both AS and A2 in one whole year, on the new spec?

Yes, you can learn the whole content and just take the A level exam at the end. No need (or point) taking AS exams.
