First, thank you very much! And to answer your question, yes I definitely submitted an addendum explaining my first quarter in college (I was a computer science major at the time, wow was that wrong for me), and why I took the LSAT three times (yes I really wanted to go to law school and do it right). To answer your second question, no I don't feel the LSAT was a good indicator of your success in law school, at all. To give you an idea, I scored low on the LSAT, even on the third try, but it was my highest. And when I say low, by LSAC's indicator, I had a 0-25% chance of getting into the law school I got into. To give you further insight, I was in the top 26 of my class right off the bat, and no I felt like I had no idea what I was doing. I didn't finish with those statistics, mainly attributable to how busy you get in school, work, and life during the process with your second/third year. You have to treat getting into law school like your full time job. Make calls, attend networking events (but don't be the overly eager beaver, leave a good impression), and really convince the people behind the admissions desk that YOU want to be their next selection. Even if you make the over the top cut for their admissions, do what you came to do, get into the school that you want. Treat it like a job. One law school admission, even if you score a 145 and don't feel like you stand a chance, is better than no law school admission. Do your thing, work it. If anybody has specific questions about law school, you can feel free to ask me for my email via comments and I'd be happy to provide.

Personally speaking, I believe they do. I just finished law school myself, and honestly if it hadn't been for my supplemental materials, I don't know that I would have had the same opportunity. Work hard on all of your materials, even if you're not over the moon with your LSAT score.
