@GIYUU_SAAN ohh, for us, we don't do entrance exams to do GCSE, we basically, you do ur end of year exams in summer, they will check math, science and english, and for math, the math teacher decides if u do higher level or foundation math, foundation is lower level, for the other two subjects, they will decide which sets you will be in for Year 10, set one is the highest level, so if u wanna reach that, u have to get at least a grade 8 or 9, so basically, A+ or in my country, an A* (The A with asterics mean A star) and yeah, you will do the other subjects u have chosen to do when u get to year 10!
