Gcse maths

i thought you were joking but yeesh i looked through your posts and you really seem very confused. u need guidance
because you want to do maths, biology, psychology for a-level focus on your maths, science and English GCSE's the most. English as well because you have to get at least a 4 unless you wanna re-sit it again. no offense, but if you don't know your time tables or your squared numbers, i seriously doubt you can get a 9 (but there's still time till the exam ig)! You need a 7 to do a-level maths, which is around 135-140 marks altogether in all 3 papers (im assuming). you can find past papers and attempt and mark them to find the level you are at right now. Science you need 7 to do A-level, psychology you need to have at least a 4 in english language. formula sheet will be given in maths and physics and highlighters are allowed in your exam.
your GCSE grades which don't correspond to the requirements you need to get onto the A-level course aren't as important. (unless you're aiming for universities like oxbridge, where they might compare your GCSE grades with another student if they're in a dilemma whether to choose you or not). There are many good russell group universities which are considered prestige and don't take into account GCSE's (as much).A-levels and your extra curriculars are way more important but just focus on getting at least 7's on the subjects you need
