You have a few options. One is to retake the LSAT and shoot for a higher score, which would help you to gain scholarship money and increase your range of schools. This is something that only you can decide, however, since it may or may not be , and Brooklyn.worth your while. If you feel that you can increase your score, I would seriously consider this option.
As far as other schools in the NYC area, I would apply to all of the following and see if any offer a scholarship to help defray the considerable cost of attendance: Yeshiva, NY Law School, St. John's, Pace, Hofstra, CUNY, and Brooklyn.
That said, there are some things you really need to consider. Don't take this as criticism, but with a 2.8/155 you may have a very hard time obtaining any scholarship offers. This means you will likely foot the entire bill yourself (probably $150,000).
Before you commit yourself to this kind of massive debt, take the time to research the job market in NYC, especially for graduates of lower ranked schools. It is very competitive, and you will likely not obtain a high starting salary. Paying back that kind of debt is no joke, especially on a low salary. With your background in biology you can try for jobs in patent law, but you will be competing with NYU, Columbia, and Cornell grads too.
It is important to be very realistic about your post grad options, and to have a Plan B. If you are happy with the idea that you may have to work as a family law attorney at a small firm, or defending DUI cases for a few years and hustling to get clients, then alright. But if you go to law school expecting a high salary and a big office, well, you may be disappointed.
I want to stay in NYC because I support my mother and my younger sister financially, and its also why I am looking at part time programs.
This is a red flag. You need to think about whether or not this is the right time to go to law school. I graduated from a part time evening program and I can tell you from personal experience that it is brutal. Law school is far more demanding than undergrad, in fact it's not even close. You will be competing for grades against other students who are just like you: smart, competitive, and ambitious. Remember all the slackers in college? They never made it to law school. It's a different ball game and will require much, much more of your time and energy.
Attending law school while working and being responsible for a family that is dependent on your income is a very, very stressful scenario. In my experience, many people who have these kinds of responsibilities end up dropping out. I'm not trying to be negative, but as someone who has actually juggled law school and a family I can tell you that this is something you need to seriously consider. Law school is so expensive and so demanding that it doesn't make sense to try it out on a "trial basis"; you must be able to fully commit your time and energy to the process or you will not succeed.
Good luck with whatever you decide, and feel free to ask any questions on part time law study.
