Actually I'm applying right now and entering a post-bacc program next fall, I really just don't want to take a glide year, i feel like i've been waiting an eternity to get into medical school (but i'm only 21, so everything may seem like an eternity). Of course, many people have been successful in getting into medical school while juggling interviews and post-bacc, but I'm assuming it will be quite stressful; but if you are persistent and resilient you can always do better and eventually get into medical school. Good Luck!
P.S. The downside of applying now instead of waiting a year is that I don't have any grades to show the schools yet. So I probably won't be reviewed until January, but you still have to submit early!
