Graduate Entry Medicine Route

Honestly you'd be better off taking a gap year (or two) and taking A-levels or an Access to Medicine course (provided it's acceptable by the medical schools you want to apply to). It's statistically easier to get in to standard entry medicine than GEM, and even taking two years out to take A-levels would lead you to qualify as a doctor in the same time or faster than doing a degree - it would also be much cheaper (you do not receive full funding for medicine as a graduate).

GEM courses don't care about your degree subject outside of a tick box exercise, if applicable. Some require a bioscience course, if you have one you tick that box - they don't care whether you did plant sciences or biomedical sciences in that case. Some require a STEM degree in general - they won't care if you did physics or physiology then. Some have no specific degree requirements, in which case they won't care if you did comparative literature or underwater basket weaving. Doing X degree or Y degree won't increase your chances of getting an offer provided that the degree is accepted in the first place by the GEM course you're applying to.

Actually, if you don't have chemistry in your degree, you'd have to have it at Alevel. If not alevel then you'd have to sit the GAMSAT- you have to demonstrate some understanding of chemistry. If you do decide to go down the GEM route, I strongly suggest that you do a degree that contains some chemistry- but I strongly recommend as others have, to do your levels/resit.

Newcastle, Southampton, and Warwick GEM will accept any degree, don't require a chemistry A-level, and use UCAT rather than GAMSAT. It's still very competitive (last year people with UCAT scores over 3000 were getting rejected from Newcastle) but it's not true that chemistry is an absolute requirement everywhere.

OP, I'm struggling to follow your reasoning - you started off talking about applying to the DClinPsy, and now you're planning to do neuroscience in order to keep your options open? You won't be eligible to apply to the DClinPsy with a straight neuroscience degree (it will need to have a certain amount of psychology content and be BPS-accredited) and there is no GEM programme anywhere in the country that only accepts neuroscience as a first degree. Make sure you are taking your info from the organisations and universities concerned, not just from forum posts.

Okay well thats 3/14 GEM medical school programs that don't require a BMAT,GAMSAT or Alevel chemistry or chemistry at degree level. But you have 4 Ucas options. Say OP opts for a 4th standard entry option- not a single one doesn't require chemistry at alevel or degree level or a gamsat
