Missed offer 😔

Hello, I received my a level results yesterday and really fumbled , for med school I needed just AAA for my offer but I got ABB with the B in chemistry and biology aqa and biology I was like 3 marks off so I sent remarking, chemistry I was 11 marks off so I’m not sure, I have 2 options now, gap year and resit but it’s going to be a hard and lonely process and also doing the ucat again , if not my uni offered me a course with a transfer scheme where I would have to do the ucat again and score rlly well on the uni exams and also around 20 ppl apply and 10 to 11 get in, my parents don’t want me to sit idle at home and idk what to do, what is the best option in this case
