Basically all podiatry schools have rolling admissions and accept nearly anyone reasonable who applies anyways.
Without shadowing... without Mcat... without X gpa... whatever. There have been threads on this, and you could probably apply and even get conditional accept from some pod schools...
but what is the thought process of not just waiting until Mcat is done?
(if you think pod school X will fill, it almost certainly will not... only a couple are semi-competitive, and they'd want Mcat)
Probably just go through the standard process of Mcat and more importantly, do some shadowing. It's a $300k-$400k+ decision.
