You need to score yourself as follows
- GCSE results
- AS results
- UKCAT
- Completed A levels
- Personal Statement (in theory, you could lie here)
Also, if you wish to survive rejection, you should be above the following threshold IN ALL FOUR CATEGORIES (applies more for a year 13 pupil).
1) Your first 6 GCSE results are at least 3 x A* and 3 x A (Maths and English MUST be here)
2) Your AS results are at least aaab
3) Your UKCAT is at least 700
4) Your P.S. shows the required "tickbox" content
OK....if you survive the above, you need to look at which 2 categories have the best potential for you and apply to the appropriate med school that measures them accordingly.
e.g. If you got got the above profile, you would have been guaranteed an interview at Leicester for 2014 applicants (58 out of 60) but over half of med schools would have rejected you because of your GCSE results.
Also, don't be fooled by the "minimum requirements to apply". It means nothing - you need to look at how they measure your categories - you then need to make sure you get the max in that category
