Could i get into Oxford university?

There is no harm in trying. Get help with your personal statement, get some relate WORK EXPERIENCE and practise interviews. I had a great personal statement and good grades, so I managed to get an interview, but I didn't do anywhere enough preparation, so I didn't get in. However, I decided to apply last-minute, so hadn't had a chance to have a proper look around etc. When I went for the interview, I didn't actually like it very much. I had applied because of the reputation, not how well suited it was to me. Especially with a long course like medicine, make sure you like it first, and aren't just applying for the prestige.
