I'll agree with drchris33 - the interview process is a pretty competitive one, so if you've been invited, that's a pretty good sign. I think a general "rule" is that a typical school will interview between 2 and 3 times as many people as they have positions for (somebody correct me if I'm wrong). I do know, however, that numbers are never the whole story. Many admissions committees look at how well rounded a student is overall, not just in their grades and MCAT scores... still doesn't explain how I got in, tho

Good luck, and feel free to contact me with any other concerns.
