Is rigorous courseload important factor?

Do medical schools take into consideration of how rigorous a students' course load (or lack of perhaps?) is in relation to their grades? Which student would be looked better? : A student who took 11 credit hours (orgo and 2 easy elective classes) and got 4.0 and a student who took 15 credit hours (orgo,research, upper level bio, elective) and got 3.8.
