Anxiety about applying to medicine with current predicted grades. Advice wantedWatch
There are also some medical schools that don't look at predicted grades, but your offer would still be AAB (at KMMS) or AAA+ (everywhere else). Personally, I don't think it would be a good idea to apply hoping to get AAA if you are struggling this badly as admissions tests and interviews will take even more time away from your A levels and if you don't get the grades you will still miss out.
Is your school aware of your mental health difficulties, and could they explain this as mitigating circumstances? This would then open more doors if you do need to resit A levels to get AAA+ or if you decided to retake Y12 having taken time out to get better.
Medical school and A levels are tough so I would really focus on getting better so you are able to get AAA+ and succeed at medical school You will always have options later such as resits and there is no point doing nothing, throwing yourself against the metaphorical wall of mental ill health, then being stressed and upset when you can't achieve the grades you need and deserve.
Also, just FYI, there are no such thing as "top" and "bottom" med schools. All schools are are GMC accredited and will end with you becoming a doctor - but they all have different entry requirements, so to achieve a place you will need to apply strategically to schools that will interview you, even if that's Keele or UEA!
