I agree with Yosh, it's always possible to get in somewhere. Yeah maybe not a US allopathic school but a caribbean or a DO school, perhaps even a med school in Australia or Europe.
Anyhow... a story to cheer you all up:
After my second year of univesity, I had a near-total thyroidectomy (and was VERY sick), still I wrote the MCAT and scored 25 (5 in verbal, 9 in bio and 11 in physics).... I applied to all 5 Ontario schools --> got 5 rejections.
So I was depressed over the next year and decided not to apply, but to strengthen my extra curricular activities (research)
Next summer I attempted to redo the MCAT but ended up voiding it right after the verbal section because I knew I failed it. I ended up applying to McMaster (no MCAT required) --> another rejection.
So last year I studied the WHOLE summer for my MCATs (I mean 3 months solid) and I applied to 20+ US med schools and 7 Canadian schools. Alas I get my MCAT scores back and I scored a 27 (7 in verbal and 10 in BS and PS), I was again depressed because my verbal killed me once again. In addition, I had some problems with my LOR (diff requirements here and in the US) and ended up being completed VERY late (in January....) so I received NO interviews and --> 27+ rejections
Seriously depressed for a few months, I decided to redo my MCATs one more time (fourth time sitting down to write it!) and apply to the caribbean (as meds is the only thing I want to do) and decided to give US/Canadian med schools one more shot. So I ended up with a 31O on my MCATs (7 verbal 12 BS and PS) and got in to St. George SOM as well as a US allopathic school.
So I'm off to the States next year and couldn't be happier... still though three years of waiting, agonizing and stressing... yes its hard but don't EVER EVER give up! keep trying and you WILL eventually get in!
