I've applied to Wolfson College. I'm 23, and I have a normal amount of work experience. I'm not a pharmacist, or a farmer, so there isn't anything in my CV they will pounce on.
I'm fairly certain they couldn't have had my BMAT score when they decided to interview me. I marked that I wasn't available across several dates and the admissions secretary e-mailed me to ask about this - she confirmed me a date and a time slot, so I assumed that meant they were interviewing me, long before the official invite to interview came. I only found out so soon because they were trying to give me as much time as possible to change my previous commitments.
Thank you all for your help, particularly the mature students.
