Im in y13 and ive submitted my ucas to study biochemistry already. Ive applied to oxford as one of my choices and should be preparing for interviews but i feel stressed with the idea i may have chosen the wrong course. I have 10 grade 9's achieved and a*a*a* predicted in alevel chem bio and maths. I also have a weeks worth of work experience in a dental practice. Im not sure if unis would hold not applying to dentistry in the original application cycle against me. I could apply in the next cycle and take a gap year, im wondering if i should try and defer entry to my courses now and then apply in that gap year, with a space on a biochemistry degree still available if i get rejected. Ive heard some people start a course at uni and apply while already studying something else, idk how this works or of its a viable option. Next option is grad entry which ive heard is more compeititive and has limited locations. Another option is i applied to newcastle biochem and they have a transfer optiom, but its very compeititve so i dont think i should rely on it I would really appreciate some advice on this whole situation!
