A side note that was reinforced to me just this weekend. Beyond rules differences, I think the most important thing to focus on are the

Now, I'm not discounting knowledge of the rules. Rather, it has been my experience that knowledge of the mechanics is an huge part of making a smooth transition from HS to college.
