Its not CCU (74K), ATSU-SOMA (58K) vs LECOM (34K). You're going to be spending a-lot of money regardless. Tuition should always be a factor but in your situation it should not be the deciding factor. If you can't handle Pennsylvania winters, you are moving across the country (idk what your situation is) and dealing with LECOM's long stated policies including mandatory attendance, buisiness causual, etc etc
LECOM is by far an anomaly in regards to tuition. Most of the private DO schools are running b/w 40-50 K per year.
You need to just run a pros of cons list of
Tuition (one factor), moving to the school and how you will be from family/SO, pre-clinical environment (mandatory attendance, OMM emphasis [Can be pro/con, depending on how its taught], extracurricular (happy students tend to be more involved in school, students with time tend to be involved in clubs), Step/Level 1 (board prep course, dedicated time, policies for struggling students), 3rd year (sites, preceptors, preparation for third year, and online modalities required for third year), 4th year (required rotations, allowed audition time, do people match at residencies you want?).
I'm sure there is something I'm not thinking of. Writing down and triaging what specifically is important to you will help alot. The fact is users on SDN don't know you or know what is important to your well being to surviving medical school.
