What I mean is that after I finish my course in anatomy (as well as other basic sciences) I will be giving a grade. After final exams I am required to take a national subject board in anatomy. I f I do not pass that exam I would fail the class regardless of what I got in class througout the semester. On the other hand, there aren't too many medical schools that require students to take this subject board exams. I do not know what you mean with shelf exams??
