Crim law, along with Torts, isn't bad in terms of reading. The concepts I think are generally more accessible, so 20 pages of crim law reading will be much easier, IMO, than 20 pages of civ pro and con law. So don't anticipate that the work will continue being quite so easy once fall starts.
The individual concepts you learn in law school more often than not aren't hard though. What's hard is assimilating it into one large body of law, and apply that huge body of law effectively, efficiently and in an organized fashion on the final, and do so better than your classmates. *That's* where the challenge is. So expect the other shoe to drop a few weeks out from the final (and be warned that you might not even realize its dropped until you get your grade back, which is often the first time people realize they went awry in writing their exam answers)
