It is very important to visit Medical schools on their open days and ask difficult questions. The answers to your questions will guide you to the more organised and student friendly University's. E.g.
Do you have personal tutors while you are in hospital placements? If the answer is no ask what support is given and by whom?
Does the University check the standards of teaching in placements?
Do you get revision time before your finals, or other exams?
How many errors have been made that have required students to redo (not resit) exams.
What is the general feed back time for results from exams?
How much time will be spent on travelling to and from various Hospitals i.e. University of Nottingham uses Queens Nottingham, City Nottingham, Derby Royal, Boston, Lincoln, Mansfield and Chesterfield and you may well have to commute back to Nottingham for Lectures that are compulsory.
If you cannot or do not drive this may cause a problem.
Large city's have large traffic problems, it can take an hour and a quarter to travel about 3 miles from the City hospital to Queens med.
