Yes LECOM has a strict administration. I believe it is a better environment at the main campus vs the one in Florida, where there have been more complains, but it would be good to check. Ole Miss and South Alabama would be stronger options. Make sure that you are considered in-state, I am unsure if Mississippi and Alabama have an agreement between their states. Unless you meant University of Alabama instead of Ole Miss, or if you attended undergrad in the other state.
You have good chances at your state schools. I think adding those 2 DO schools and maybe Oklahoma State (if you improve your score) would be good. ACOM had good rotations I heard, but I am unsure if they are centralized.
