Leroy is right on about Black Monday. It is all doable if you are willing to put the time into it. My advice for those coming in for January and future semesters is the following
1- Stay on top of the material. It may not seem like a lot each day but it does pile up.
2-Dont go and try to memorize the anatomy it is more important that you understand it. I am sure Leroy, Snazzy, Infinite, and futurephysian will all agree with me on this. If you understand the concepts and what is going on everything else will fall into place.
3-Try and form a study group when you get here. It does help a lot. For me it meant that the weekend before the exam i was not panicking because I knew what i needed to work on from reviewing with my group.
