Hey guys,
Having helped run the UCAS admissions days for two and a half years for the School of Maths, I thought I'd share some advice.
Dress Code:
You can wear whatever you like. My tip would be to dress as you would on your first day of university. So wear something nice, but not outrageous. You want them to remember you for your mathematical aptitude, not how ridiculous you can look.
The Interview:
The interviewer's job is to see if you are a good fit for the maths department at The University of Manchester. This means that you have to be able to cope with independent study and have an aptitude for maths.
Even if you don't know how to answer the question at hand, pause, take a deep breath, and then explain how you would go about answering the question. Also, remember that the interviewer is guiding the interview, so try not to go off on a tangent or waffle too much.
It's also important that you brush up on C1, C2 and FP1 as these are the modules they will expect you have taken by the point you've come in for interview. Of course you could revise all your modules, but this isn't practical.
Also, make sure you know your personal statement back to front and you have a few questions for your interviewer. If you've got any mathematical curiosities that you would like to share with them then do so - it goes a long way to showing your interest in mathematics.
Final Bits:
On the day of your interview, remember to be calm, relaxed and take the opportunity to learn as much about Manchester as you can, as you may very well be living there for the next three years. Also, think of some questions for the students showing you around. It's their job to answer your questions.
Cheers
Darren
