Interview questions There's a torus/ring doughnut shaped
space station with 2 spacemen on a spacewalk standing
diametrically oppositie each other. Can then ask a variety of

spaceman B, what angle and speed should they choose (stating
any assumptions made, e.g. that gravity = 0)? (submitted by Oxford applicant) Comments

 Recommended resources for interview and university preparation  Yet another University of Cambridge funded project to help people get into top universities. Look a the "prepare for university" sections to get a feel for the level of interview questions.
  Video of example Oxford interview in two parts.

Recommended books  Really useful book of advanced math problems which is recommended ahead of STEP, MAT, PAT etc.
"This book is intended to help candidates prepare for entrance examinations in mathematics and scientific subjects, including STEP (Sixth Term Examination Paper). STEP is an examination used by Cambridge colleges as the basis for conditional offers. They are also used by Warwick University, and many other mathematics departments recommend that their applicants practice on the past papers even if they do not take the examination. Advanced Problems in Mathematics is recommended as preparation for any undergraduate mathematics course, even for students who do not plan to take the Sixth Term Examination Paper."   Perhaps a little oldfashioned by modern standards but great material and just the right level for university preparation.
"This volume features a complete set of problems, hints, and solutions
based on Stanford University's wellknown competitive examination in
mathematics. It offers students at both high school and college levels
an excellent mathematics workbook. Filled with rigorous problems, it
assists students in developing and cultivating their logic and
probability skills. 1974 edition."   Amazing book of fun (but extremely challenging!) interviewstyle questions (including many from our list) by Oxford Professor. Highly recommended for anyone planning to study mathematical subjects at university level. More physics problems than maths problems so less specalised than the previous two books, but still very useful for interview and university preparation.
“Entry to selective universities will often require students to demonstrate that they have engaged in supercurricular activities which develop their awareness and understanding of their subject. Thomas Povey has provided in this book enough supercurricular content to keep an aspiring mathematician, physicist, engineer or material scientist (and their teachers) happy for months. For a parent or teacher who wants to proactively support a student in preparing for entry to a competitive science or maths course this is a nobrainer purchase.” —Mike Nicholson, Director ofUndergraduate Admissions and Outreach, University of Oxford (200614), Director of Student Recruitment andAdmissions, University of Bath
