Thanks for the input everyone. Like 2THDDS said, some schools, like Nova, ask what other schools you've applied to in their secondary app.
The applicant who told me this was convinced he got rejected from Nova because of the number of schools he applied to. He and I had very similar stats... >3.5 GPA, 22-24 across the board for DAT, great ECs, >100 hrs of shadowing, etc. I, too, was rejected from Nova almost immediately...no more than a week after I submitted my secondary app, and I applied to 18 schools. But after reading some of your responses, I guess it must have been another reason why I was rejected from Nova so quickly. Just kinda sucks not knowing why you were rejected, especially so soon after you submit your secondary...
