As a 2L, I can say things get both better and worse than 1L. The work isn't as stressful as it was last year, namely because you know how to read cases and what's important. That being said, there can be more coursework, depending on the professor, which is partly because the professors move a lot faster. Its easy to start feeling lost and "left behind." Taking classes that interest you is fun, and it is nice to get away from the 1L grind. You take a lot of stuff that you never thought you would, which is interesting because you may find yourself liking areas of law you had never considered before. With the exception of some of the "harder subjects" (tax comes to mind for some reason), I wouldn't worry about taking classes for the BAR. This is what BARbri is for, and a lot of friend that have taken the bar exam said Barbri will teach you what you need to know.
2L is also worse than 1L in several ways; the job search starts immediately, and is much more stressful. If you're on journal or moot court, you're adding in additional research, cite checking, drafting, revising, etc. on top of an already full schedule.
