I'm not considering cambridge at all, It'd most likely be Leeds.
these are their entry requirements:
Normally 3 A levels at AAB including Chemistry. Applicants are required to offer a very high standard of achievement in at least three subjects at A2 level. General Studeis not accepted.
Apart from chemistry at A2 there is no restriction on the acceptable A2 or AS examination subjects (other than General Studies), provided that they have a sufficient academic base. Where mathematics and biology, or Dual Science are not offered, a B pass or higher in these subjects or equivalent must have been obtained at GCSE level.
