Hello my son did really well in his gcses this year and 2 of his subjects he was 1 mark off the grade above . English language he got an 8 (1 mark off a 9) and computer science he got a 7 ( 1 mark off a 8) . Chemistry he was 3 marks off a 9 . Is it worth getting these checked ? Anyone done this ? Don’t want the marks to go down . Thank you
