I am pretty much in the same situation as you.
I have 8 exams, 3 of which are resits and it is so daunting! I have the 3 in May and then my A2s in June like you. I'd say prioritise your time now to the resits but don't ignore the fact you have A2s. My revision timetable is set out that I learn all topics, but then as it gets closer to the resits I concentrate on them. You don't want to come out of your resits and then only have a few weeks to revise for the A2s, which is why I am revising them simultaneously.
Hope that helped, and I'm glad I'm not the only one who has 8!
