2x interviews (20-25 mins)
Based on A level knowledge, questions gradually harder
Revise biology A level; mock interview
Don't overanalyse after
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.
2 interviews about 25min and 20 min at 9am and 11am. 2 interviewers each asking questions about a different topic from their speciality.
Started with basic questions from A level biology and then questions got gradually harder to build extra knowledge from what we knew.
Topics: cell biochemistry with an estimation question which required some basic calculations, bacteria, NHS, discussion about a medicine I mentioned (previous knowledge not required)
Revise biology A level (although content not hugely required)
Try not to think about the interview after. I said a lot that I would have liked to have changed and missed some points that were "obvious" but still got a place. Be confident about answers or thoughts.
