If you can do well enough on the LSAT to get into a TT I would encourage it. But if all you can muster is a TTT or TTTT, please think carefully before doing it. (You won't.)
BULLCRAP. Any graduate from any school can get a job in law. This LSAT is complete crap, and not every school relies on it so heavily.
I work at a law firm that hires interns out of Harvard and Yale and guess what? All of them have sucked. They all came to us with a sense of entitlement and they all cheated their way through their internships (by claiming graded credit when they didn't fulfill their obligations to the law firm). I've witnessed a couple of them (from Yale) flunk the Massachusetts bar.
So scoring high on an LSAT and getting into a top tiered school doesn't mean the student's not an a-hole. It just means the student's an a-hole with a sense of entitlement.
TTom, I highly encourage you to GO FOR IT. Study up and take the test a third time in two years. You seem like a thoughtful person who's discouraged, and don't let the negative blowhards on this site discourage you by saying you're not cut out for it.
If you want it badly enough, then you're cut out for it. GO FOR IT. All you really need to practice law is admission to a state bar. Period. Build your contacts now, do great in whatever school you attend (on whatever tier you can get into) and GO FOR IT.
I wish you all the best. And to the blowhards who are negative, I wish all the worst.
