I'm a retired GP (either that or this is a long career break, I'm not yet sure!!). My daughter was a resit reapplicant 2 years ago having originally applied 3 years ago (3 interviews, no offers, AAB). She is now a second year at Peninsula and loving it (4 interviews, 3.1 offers, A*A*AA).
We all know the stats and how tough this is but it does work out sometimes so don't lose heart.
I have supported loads of potential medics over the last 2 years most of whom were on their second application cycle and my word of advice to you all is that interview skills can be learned so don't believe anyone who tells you that you should turn up to interview 'natural' or 'unprepared' - they are either numpties or else being ruthlessly competitive.
Apply tactically, prepare well and reap the rewards…
Oh and don't feel like second class citizens; re-sitters are more determined, more committed, more mature, have higher tariff points, are more confident, more worldly wise and make really solid (dare I say better?) med students/doctors; that's why the re-sit-friendly universities put up almost no barriers to them: they know that they're onto a good thing and would prefer that other med schools don't wise-up to it!
Good luck!
