I am soon to enroll in a standard community college in the U.S.A. that, along with the traditional Fall, Spring, and Summer semesters, offers split Fall, Spring, and Summer semesters--Fall A, Fall B, Spring A, Spring B, and Summer A and B. This means I would be enabled, for example, to take Chemistry 1 and Physics 1 during Fall A, and Chemistry 2 and Physics 2 during Fall B. And so on in the following spilt semesters. Do you see my taking pre-medical classes this way--Fall A and B, and so on--as being a problem? And what if I bulked O Chm 1 and Phy 1 into the A term and O Chm 2 and Phy 2 into the B term--the normal time frame of a standard semester? Would this be too rigorous for GPA success?
