Hi , I did quite poorly in My AS exams, I took Psychology, English lit, Politics and Biology. I got CCEU , I have changed sixth forms and i have changed my subjects to Biology , chemistry and maths. my new subjects are A levels with no AS exams , so i'll finish my exams in 2019 meaning I would have spent 3 years at sixth form. Does this still count as retaking as it isn't like i had done my A level exams. Is it still possible that i can do medicine?
