If you have a definite field of interest, you should include this among your criteria for choosing a law school, but do not make it the sole factor. Keep in mind that many students change their mind about a field of specialty once they are in law school. Some schools, such as the USC Law School, will not consider you for scholarships unless you have applied for fiancial aid. If you do not qualify for financial aid, you will still be eligible to take out commercial loans. The law school will be able to provide you with a list of preferred lenders that may have special rates for their students, but you can also receive loans from your bank or credit union, Sallie Mae or other commericial lending corporations.
Some law schools do offer part time programs.
The admissions stats for part-time programs tend to be the same or a little lower than the full time admissions stats for a given school. Most part time programs allow you to graduate in four years. All in all, we feel it is better for your education to attend law school full time, but if that is not possible going to school part time is a viable option. Since LSAT scores are averaged together, it is generally not to your advantage to retake it, even if you scored several points lower thant you practice score, which is normal. Equally, if not more important.
