We normally do English where we get 2 grades (language and lit over 4 exams), maths (3 exams but 1 grade), science (get 2 grades over 6 papers, 2 for each science and if you do triple [like I do] you get 3 grades, then three/four other subject grades depending on if you do triple science (how many exam papers depends on the subject and exam board) so over all you tend to get 9 grades for GCSE qualifications although I’m sure Izzy’s school had arranged for her to take less subjects so she would have come out with 7/8How many GCSE's do you normally take in England? I always assumed because they were pushing for Isabelle to sit English and History this year, she'd then focus solely on maths, business and anything else she's taking next year.
edit: this is an extremely basic summary, for example English also has a listening/speaking grades integrated into it aswell so please no one come for me
