Your GPA doesnt replace your MCAT.... if your score is below average, retake the MCAT
the program is not just for DO schools. Since I finished that program, I actually do know what Im talking about.
I emailed a few admissions offices asking them what they thought of the program and they all know it is a "mini med school" program and they treat it as such.
If you perform well, it will show that you can handle med school curricula.
However, I would not recommend taking that program with a 3.68. most people that attended it had 3.0-3.5. If your MCAT is truly the only issue, I would say retake the MCAT after a dedicated study schedule.
