Hello,
It is very much possible. Access to medicine offers an unconventional route to medicine, for those who do not have sufficient Alevels required to get into medicine. You would need at least B/6-9/A* in GCSE Maths and English. So i’d advise retaking those first. Self studying is hard, but possible, YouTube and online resources are available. You would need to contact colleges which offer an Access to medicine course and ask about their entry requirements, make sure they are approved centres, do not attempt a distant learning Access course as they are, from my knowledge not accepted by medical schools. Once that’s done, you will need to take your UCAT.
The hardest part of the journey is the daunting Access to Medicine course, a 12months intense Course of 2 years Alevel Maths, Biology, Physics and Chemistry jam-packed into 12months. The Access course is your route to Medicine.
So, yes, it is possible. One step at a time. You just have to be determined, hardworking and resilient. You can do it.
