More details would be helpful, but I would recommend asking for your scripts back ASAP and remarking if you are close to the next grade boundary. Again, depends on what you got and what you need to study at A-Level.
ive just got my gcse results and i didn’t get a high enough grade to get into biology and the only thing i’ve wanted to do is medicine what do i do
If you want to take Biology for medicine then the only thing you can do is retake it, unless you were close to a grade 7 in which case I would consider getting it remarked.
