Will I be asked questions about biology in a medicine interview even though I don't have it as a subject? I have done a lot of reading on it (which I have mentioned in my PS) but I don't have the detailed knowledge you get from studying it as a subject in school. Or am I only going to be asked questions on physics, chem and math as those are my subjects? Also, how much of the interview is about work experience/ personal statement and how much is on science questions? Should I revise physics and chemistry or just try to relax before the interview?
