In reply to wednesburywench. I hope it doesnt sound like im having a go at you here, but i've read on several occasions, over some 3 forums, how you seem to doubt your ability to meet the grades for your offer - just because of your school.
Basically i was in a similar situation to you. Last year i applied for deferred entry (for 2005) for medicine at KCL, Manchester, Liverpool and Leeds.
Coming from a school where the average GCSE grades are 5 A-C's and where the average A-level scores are CDD, where nobody has applied for Medicine since the last so many years, was an extreme struggle.
I was actually told that id have 'to go it all alone' since none of my teachers had any experience with personal statements or what type of references to write to make me look like an able prospective medic.
Like ThePenguinMafia..i was in classes where the teachers were making us work at a pace so that we would maybe get C's as the majority of the people in my classes only needed C's to meet their offers. But i had to get A's and this meant i basically had to cover most of the work myself, in my own time. Eventually i decided to leave college after the january exams and studied at home for the rest of the year.
When it came to interviews, i turned to teachers for help since id read on other forums how students had mock interviews from teachers. My teacher gave me a telephone number, called and i was told that this person wanted to charge me £80 per mock interview session (20 minutes).
I knew no other medical applicants/medstudents so really i was kind of lost as to what to expect. But somehow, in the end i ended up with 4 offers, and got 4a's. I'm now gapping and off to KCL in september.
What im saying is no matter how 'crap' your school is or what its average grades are etc, If you're 100% committed and determined then you should have no problem getting those grades. It might mean you'll have to put that extra bit of hard work in, so do it and this time next year im sure you'll be in medschool. Good luck!
