Time is a luxury not to be wasted. Just as in college, T.V. is an enemy. Learn to do several things at once. Also learn when to take a break from it all. Most of the day is filled with lectures, labs and small group activities.
Some medical students end up missing lectures because they fall behind in their studies.
However, many medical schools have a note taking service that transcribes lectures. These are then distributed to everyone so that they can be reviewed at any time. Try not to fall behind. Once you fall behind it leads to cramming for tests, and crammed material is forgotten quickly. And it just keeps coming.
