I'm in year 11 and want to take A level computer science but am not doing it for GCSE. I am predicted 8s for all sciences (triple) and 8 for maths. Do I need to do Computer Science GCSE to do A level or will i be ok? I am also worried about not knowing any of the prior knowledge of GCSE that is probably needed, however i do have a knowledge of the basic terms and basic ideas about logic circuits, and a bit about html and python too. help
