How should i spend my time

Hi, iam am sitting biology, chemistry, Physics and maths as levels in may. The exam board is ccea, i tried making notes but it didnt really work durning the first turn. I wanted to try making flashcards but have realised it would take a while to backlog topics
Should i;
1) ignore current topics to try and catch up previous topics.
2) spread out the making of flashcards, but not giving me a lot of time to use them
3) not backlog and just focus on the new topics
4) spent 4 weeks catching up and doing new topics but i may be burnt out by may.
I have already tried looking online but i coulnt fine any. Please let me know your advice or any places where i could find ccea flashcards. Thanks

1) No you should not ignore current topics. Focus on understanding current topics and supplement this revision with older topics (bit by bit). Say one topic a day.
2) I personally didn't use flashcards in A levels (only did during GCSE = worst decision) as I find them a waste of time.
3) I got straight As and did the same A levels (except physics) and this is my biggest tip:

Hiya fellow ccea applicant i did my a levels in 2022 so remember it well
I’d make sure u prioritise what u dont know! Do lots of practice papers and revision questions to solidify knowledge
Good luck!
