Out of the schools I applied to here is what I have:
Mandatory: ACOM, BCOM, CUSOM, LECOM (most class time for LDP, following by PBL, then DSP), LECOM-B (just PBL)
Not Mandatory: KCOM, SOMA, DMU, NYIT, NSU, PNWU, PCOM, Rowan, UNE, WVSOM
Note: By not mandatory, the basic science lectures are not required, you obviously still have to go to the labs, OMM, Clinical Skills, and any other "doctoring" classes
