Yeah, my application changed quite a lot. I came to realise that my main problem first time around was too much emphasis on the academic side of medicine in my personal statement. I think that prevented me from getting interviews at Keele and Nottingham last year. To improve that this year, I vastly increased focus on the doctor-patient relationship and seeming like I want to do medicine so that I can basically help people and because I appreciate the rewards of it. My personal statement is, in my opinion, about ten times better mostly due to restructuring and better choice of content. Obviously, I added gap year plans too, including more work experience, a second job in teaching, fundraising and extra AS levels.
Given that, I still think having obtained the grades does make a profound difference to your application because almost every applicant has the grades required and many have much better than the grades required in their predictions, which not all of them meet. Basically, having the grades already means there's no doubt in them that I have the ability and the study skills.
Similarly, simply being a reapplicant is a great factor, because they can be confident that you do really want to do medicine; you didn't just go for the fifth choice because you wanted to go to university or because it would be inconvenient to try again in three years' time, especially given that grad. entry is even more competitive. You've shown a huge dedication by giving an extra year of your life to getting that place - perhaps even more so for 2012 reapplicants as they still want to pursue medicine despite the tuition fee rises.
My UKCAT went up from 635 average to 682.5 average this year, mainly due to putting more time into it as last year I had summer schools and work over the summer etc. holding me back. My best hint is do every last mock UKCAT you can find (I used three books, the Pearson VUE official tests and two Kaplan tests given to me by a friend who attended the course as well as various internet resources).
The only place I have applied to again is Nottingham University, because I really love the course there mainly (two degrees at once - I would intercalate wherever I go, I think, but Nottingham saves time). My other three choices of 2011 entry: Cambridge, Birmingham and Keele, are not in my application this year. This is basically because I decided to play more closely to my strengths. There isn't really an order of preference this year, because I really just want to get into medicine after last year's catastrophe.
Any more questions?
