Keep your options open with medical schools as even the most highly qualified students sometimes don't get places. Get lots of healthcare work experience in hospitals, Clinics, old peoples homes, hospices- this will really set you apart from the rest of the crowd. You can also leave out the C you got in D&T on your application as its not a core subject. You have just finished your GCSEs so don't pin-point a university on reputation, go visit lots of universities work really hard and remember to have some hobbies as well- the more unusual the better!
Also most med schools don't require 4 A2, I go to the best state sixth form in the country (not boasting, its statistically true) and only 10% of 2200 students carry 4 subjects to A2, do double maths if you really want an extra A level.
