Do I need to take both Physics Mechanics and Physics Electricity and Magnetism?

texaspg’s comment is true. It is not necessary to have calculus-based physics to do well on the MCAT. On the other hand, a group of pre-med advisors at my university did a study of the MCAT performance of students who had taken the calc-based physics vs. non-calc based physics option. The students who took calc-based physics did better (I think this was specifically the science part of the MCAT?) than the students who took non-calc based physics. This could be entirely an effect of self-selection, where the stronger students opt to take the calc-based version.
