Relax because it makes it so much more enjoyable.
Remember this advice isn't official. There is no guarantee it will reflect your experience because university applications can change between years. Check the official Cambridge and Oxford websites for more accurate information on this year's application format and the required tests.
Also, someone else's experience may not reflect your own. Most interviews are more like conversations than tests and like, any conversation, they are quite interactive.
My interview was in early December. I went to the
We discussed entropy and enthalpy for the chemistry questions. For the bio questions, we discussed lots of different stuff, and how i'd construct an experiment to test stuff given the conditions they gave. But I didn't remember everything and if I got a bit stuck it was okay to ask the interviewers more questions.
Being relaxed really makes the interview easier and more enjoyable, as you can just enjoy the challenge and experience rather than worry about your future.
