As far as law school being hard work, it is extremely hard work to do well. Moreover, as hard as you work and as smart as you may be, you just might not get the hang of how to do well on the type of tests many law profs give. So your hard work will not bear results.
OTOH, it is extremely difficult to flunk out of many if not most law schools. Therefore, it requires no great effort for a reasonably intelligent student to graduate with a C average. You can raise that in your 2d and 3d years by taking seminar courses that are graded on essays or takehome tests, instead of the 3-hour in-class issue-spotting marathons. Then all you have to do is apply yourself reasonably towards a bar review class to pass the bar and - presto - you are a lawyer. No requirement that you know jcakshit about any specific area of the law.
Granted, graduating in the bottom quarter of your class will affect your ability to compete for certain jobs, especially depending on the market when you get out. But should you get any job, the relative significance of you GPA/class rank will decrease rather quickly as you gain experience. Plus, you can always hang out your own shingle, and the boss won’t give a rat’s ass about your GPA. Also, if you are getting your law degree merely as a step towards some other goal, GPA may not be all that important as having the degree.
Personally, I found most of law school extremely boring. Most of the classes I found most interesting - international law, law and economics, for example - have nothing to do with my daily practice.
What I do all day every day (when I’m not posting to the SDMB) is essentialy federal civil procedure. And that class, as taught at the decent state school I attended, was absolutely incomprehensible. Something about hitting tennis balls back across the net? WTF?!
Depending on what line of work you go into, classes such as Con and crim law may have little to do with your practice. But they will help you better enjoy TV lawyer shows and newspaper articles - adds a different level to your understanding of many issues. And you will wish you paid more attention in property law and contracts when you buy a house, and buy appliances or hire contractors.
Just wanted to point out that if you just want a law degree for whatever reason, “hook and go” can be an appropriate approach.
