I only did math, i'm in year 10 and the exams are meant to be taken in 11 (so i took accelerated which is the equivalent of your AP) got an A
Finished my iGCSE's last year. They're really not as bad or as important as people make them out to be (in my opinion)
I got straight A's (10 subjects), congrats on your early A. Good luck for next year.
