Is it too late to apply this cycle? I know the site says June 1st is the deadline, but is it realistic to apply within the next week and have some success?
People have applied later than you and have gotten in. Just check last years (or years earlier even) threads. The application is not even due till May or June I believe so you can still submit and have a decent chance I think.
As for filling out the AMCAS, I think that's because if you get into this program, they are basically holding a seat in their next medical class so they don't want their students that they're investing a lot in to go to or even apply to other schools (among a bunch of other reasons I'm sure). Also it takes out all the guessing of where you end up, which I think is the beauty of this program. If your accepted you know what to do - get above the equivalent of 30 on the new MCAT (if you haven't already done so) and maintain a 3.5 GPA in the program.
That said, you can fill out an AMCAS if you don't hear back from them when the apps open up for AMCAS, but if you are admitted and attend I think they'll ask that you withdraw your application, which you shouldn't need because I think they expect you to meet the criteria and continue to their med school. Also, I think for those same reasons, I don't think they'd want their students filling out AACOMAS either.
If you are not willing to commit to Temple if admitted to this program, I'd recommend Georgetown's SMP, where theres plenty of time to apply to left. This may POTENTIALLY (remember only potentially) give you more (not necessarily better) options for medical schools. Check out their forum and website for more info.
Hope that helps! Best of luck!
