Hey there. Advice you got so far is useful, but when it comes to the crunch most applicants for Med you would be competing will have A* in most GCSE subjects. Chem, Bio, Maths, English compulsory in my opinion at GCSE level, and at AL A* in Chem is compulsory for some medical schools such as Cam and Oxbridge. So, at GCSE do well in Chem, Bio, Maths and Eng, and do other subjects, ie; arts, history - i mean subjects easy to get A* with minimum effort at GCSE level. When Unis decide on which applicant to give an offer they will look at your GCSE to see if you had a good set of results in the first sitting because if you have had to repeat at GCSE to get good results, that means you are likely to struggle completing your med course. Getting good grades at GCSE is very important if you want to be selectedto study med. Don't under estimate.
