MEOW!
I'll offer my advice. Don't go for grad entry, it's more competitive than what it is for people with A Levels. My 3 housemates applied for med as grads this year and they were rejected from all 4 choices w/o iv. So don't assume as a grad you'll get a place, you might be stuck in the same position as what you are now.
Also, you'll have to come up with the money yourself, and with the fees rise it's gonna be ridiculously expensive for you. They'll be removing NHS funding for the 4 year courses in a couple of years I reckon, they're already doing it with things like paramedic science.
Your chances of getting in depend on where you apply. Diff med schools favour different things.
