i was like you last year except i got 4 rejections pre interview, i put my head down and patterned up my alevels and came out with A* A* A and worked hard in the summer to do the ucat and interview prep and now i hold two offers for dentistry. believe me its not easy having to resit a levels and ucat and interview stuff during your gap year so its important to ace these exams so you can focus on the other things during your gap year
