I will say law school and any educational experience is what you make of it. Many people at my school complained about 3L and the pointlessness of it, but I accomplished a lot during that year I participated in two mock trial competitions, took some great writing courses which lead to me having solid writing samples, had two great internships, and developed solid relationships with professors. If you sit in the back of the class and just want to get your degree then 3L is a waste of time, but it is the system and you might as well make use of it while your in the law school bubble.
Let me explain my third year of law school. I only had 22 credits left, so I was able to work as many hours as I wanted and not violate the rules.
I wasn't an amazing student, but by 3L I had things figured out.
3L GPA was 3.8 on a 3.0 curve.
Law Review Editor (4 credits)
Moot Court (4 credits)
30 hours as student licensed intern (student practice rule)
Faculty research assistant (I helped a professor write a law review article for another school) (3 credits)
And I had 11 credits in class, split between two semesters.
Was that a waste? Absolutely not. I honed my skills during 3L, but I really didn't receive "instruction" in the same way I did as a 1L. It's tough to swallow that heavy bill when you really aren't using the school resources in the same way. I had a friend who managed to get 25 of is 90 credits from externships. Yes, he paid $800 per credit to work for someone.
Also, while I understand that some people are uncomfortable with commercial outlines, I really think that, for most people, reading every case and taking vigorous notes after your first semester can be a massive waste of time. I think analyzing citizens united by saying, "Hey, Corps are people dudes!" is obviously deficient, but a full analysis of the entire case and dissent, and a study of the history of those justices and why they voted the way they did is not necessary or helpful to most attorneys. There is a middle ground.
