If you take the jan MCAT, you'll get your scores back in late february/early march. Aplying that late limits you to the schools that you can apply too, since by March most classes will be 90% filled. I know someone who applied in march to bradenton and got in 3 days before orientation off the waitlist. So you'll have a shot, but it will be slim. my advice is to apply for the next cycle, since although u might get into a DO school with late a application, it might not be the DO school you want to go to.
If you dont mind me asking, why are you taking the MCAT so late?
