You should really go to LSAC.org and check out the employment statistics for the schools. There is data on % employed and average salary. You may also want to ask career services about OCI (on-campus interviews) and which firms and how many come to your school. If you want a good job, you are probably going to have to get really, really good grades to compete. New York has a ton of law schools, plus the NY firms recruit from all the other top schools in the country. It's a tough market.
On another note, my boyfriend (an attorney) and I ran into someone he knows. He graduated from college early and was going to law school at St. Johns. I think he finished one or two years of law school and is currently taking a year off. Judging by the way he said this, it seemed like he wasn't doing well in school. After he left, I wondered aloud why he didn't take some time off, retake the LSAT, and go to a better school. My boyfriend agreed that that's what he should have done, especially in a market like New York. Remember, a higher LSAT doesn't just mean a better school, it also means more scholarship money.
