Unless there's a huge difference in $$, this is really a no-brainer.
MD> DO= knock out MSU DO.
MSU CHU I'm pretty sure has been ranked under their DO program. I don't pay too much attention to rankings, but some applicants do. Their clinical training leaves a lot to be desired and their new curriculum scares the hell out of me. I was accepted there last year and withdrew my application as soon as I was accepted somewhere else. From what I remember, they have tons of mandatory attendance during business hours, tons of "intersessions" and not a lot of independent study time, even leading up to step.
Wayne has great clinical training and will leave you alone to study a lot more than MSU will. Now that I'm in the thick of things, I honestly think whichever school is the most hands-off is the best option.
