My wife is in Law School and a member of the Federalist Society. They sent out information about a free Internet Course On American Constitutional Law. I can't say that it is good or not as I have not gone through it, but it might be a good way of getting a quick (relatively) review of Constitutional Law in a moderately pain free way.
I in no way endorse this class in particular, just the idea of getting a "quickie course" on Con Law for free should be pretty enlightening. I plan to start it and if it is good, continue.
The lectures start on January 17th
