As you already know from this past cycle your chances for a MD acceptance are low. DO schools do need to fill their classes so if you apply to many schools you should receive more interviews. If you apply to MD schools again I suggest these schools as a PA resident:
Drexel
Temple
Jefferson
Penn State
Geisinger
Seton Hall
Vermont
Quinnipiac
New York Medical College
Albany
George Washington
EVMS
West Virginia
NOVA MD
Oakland Beaumont
Western Michigan
Rosalind Franklin
Creighton
California University (new school)
If you want to save money on application fees, there is no point in applying to Wayne State, Rutgers, Wright State, Cooper and Central Michigan. They are state public schools that give a strong preference to their own residents and accept very few non residents with your stats. Pittsburgh is a far reach.
