Hi I will be applying to Oxford university to do mathematics and I've narrowed my college choices down to Exeter and Keble. For those that do mathematics at Keble/Exeter/Oxford, could you give me some ideas of how the style of the interview is like and whether or not there is a written test given at the college itself because I cannot seem to find the information online. Also, is Keble and Exeter considered one of the more competitive colleges for mathematics? Thank you.
This is how Oxbridge students do it.
