DPM and MD students at TUSPM will not be able to sit the same classroom and take the exams together simultaneously for the basic science courses any time soon. The main reason is that the DPM and MD classrooms are in two different locations.
As for your assumption that TUSPM and Scholl students are not upheld to the same standard as the MD students on the basic science exams is rather interesting considering you do not even attend either of these schools. With exception to the TUSPM anatomy courses (Gross Anatomy, Lower Extremity Anatomy) and microbiology course, the remaining basic science courses are taught by Temple MD faculty only. In regards to the exam questions and the level of exam difficulty between the MD and DPM exams, they are pretty much identical. This is pretty evident by comparing the exams of the DPM course with the corresponding MD course. When I was a TUSPM student, the Pathology course director would compare the DPM class average with the MD class average for the Pathology course annually since the DPM and MD students would take the Pathology course simultaneously. Of course, things may have changed at TUSPM since I have graduated, especially with the new changes in the Temple MD curriculum.
As for course grading, I think that TUSPM students are graded more harsher than the Temple MD students. TUSPM students class grade is a numerical grade (0-100) based on a weighted average of the course exams and/or practicals. If the course grade is below 70, the student will fail the course. On the other hand, the Temple MD student's course grades are based on Honors, High Pass, Pass, Fail system. Hence, if the Temple MD student were to get a course average of 65 and the class average was 65, the Temple MD student would get a Pass for the course. On the other hand, if TUSPM student were to get a course average of 65 and the class average was 65, then that TUSPM student (along with 1/2 of the class) would have failed the course. I know that the example is rather dramatic but it does make a point.
By the way, doesn't this posting sound familiar, krabmas?
