<p>I’m not experienced with the UK college system but as I’ll be applying to Oxford this fall, I’ve done some research. Universities like Oxford and Cambridge care first and foremost about your transcript and test scores. You can see their respective requirements online at their websites.
Secondly, they’ll look at your personal statement where you discuss why you want to study that particular subject (many of which have entrance exams you have to take before you can even apply). In this statement, you can incorporate your ECs and show how they fueled your passion for the subject.
Thirdly, they’ll look at your interview performance. You can find what they ask online at their websites.
However, 80% of all students that apply to these schools receive an interview so it truly will be the interview that sets you apart. The schools themselves even admit that the interview is probably the most important part of your application.</p>
