yeah, but i dont know your level. the gcse only needs 140h of total learning, and for context i had like 900h of fortnite, and a lot of people get 4s. in my year, it was 51/240 in aqa (higher) for maths, so if you are god awful at maths, like you need divine intervention, you may struggle with a 4, but if you are driven im sure you can pull it off. Im not very sure how my uk exams compare to international gcses, but im guessing theyre a bit harder (from my experience of looking at IALs in chem and physics)
