Nope, you can't think that way. I'm not saying you're hosed. Far from it, in fact. But I'm trying to give you a realistic picture of what you're facing. I know so so so many people who have come down here and been dismissed for failing a term, or at best, forced to decel and take an extra term of courses. This is Not An Easy Road to Take to becoming a doctor. It requires that you be acutely aware of your deficiencies, and understand why you didn't get into a US school. You're in a position where you don't need to come down here, and I'm trying to urge you in the strongest possible way to fix what you need to so that you don't have to come down here. Seriously. Study your ever-living ass off for the MCAT, score a 29 or so, and apply broadly, and you can ignore all of the headache of coming down here. Four months of hellish studying is preferable to coming down here, especially when it won't set you back in terms of application time.
