shorter classes often,... then your brain is more alert/less fried for each class. I have been taking TPR for the april MCAT (which is in less than 3 wks!!! <img border="0" title="" alt="[Eek!]" src="eek.gif" /> ), and my classes are mon-thur, 4-6:30. I like it spread out. I know people taking it less days a week from 4pm-9:30pm, and sometimes they just go home early at 6:30 cuz they're bored or drained.
