In the recent end of year exams (year 12) I got a B (computer science) and 2 E's (physics and Maths). On my schools prospectus (for 2023/24) it states to get into year 13 I need at least a minimum of 3 Es in all my subjects (it's been like this for about a decade) which I've achieved (My predicted grades forcomputer science is an A, physics is a B and for Maths an E). However, now the school is saying now I need a minimum of 3 D's to get into year 13. I'm unsure of what to do, I was a few marks off a D in Maths and physics but I know they probably won't accept that. What should I do now, would I have to retake the year or would I be able to appeal?
