2x interviews; 1x test
Problem based
Make sure you're really comfortable with A level
Try your best
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.
First I had a
My first interview had one graph sketching question, where the interviewer lead me through sketching the graph of a certain function, and then I had to derive a Physics formula, which I would later learn in A- Level. The second had one question based on series, and another on geometry, with the first then relating to Chemistry. It was hard to tell how they had gone at the time - they don’t really give anything away - but I felt like I did my best!
It was quite hard to prepare for them well, as they test you on new concepts to see how you respond to them instead of things you already know. Making sure you’re really comfortable with Maths you’ve done at A-Level is probably the best thing you can do!
Just try your best, and don’t worry about it! (Easier said than done...)
