Based on my background/profile, would it be a good idea to go to law school?
Well, not to sound snarky but it depends on whether or not you want to be a lawyer.
If you really want to be a lawyer, and are willing to make the necessary intellectual and financial commitment, then yes. If you are just trying to figure out what to do for the next few years and law sounds kind of interesting, then no.
Law school, the bar exam, and the job hunt are huge undertakings. You should only do it if you are sure you want to be a lawyer, an only you can answer that.
I would definitely take the time to find out what it's really like to be a lawyer (very different from TV and movies), and think about your long term goals. Law can be a great career but it's not for everyone.
I'm not sure what a 68% translates to in GPA, but if you want to go to law school start preparing for the LSAT as soon as possible. Your LSAT score is a huge factor in admissions, and a high score can help with obtaining scholarships.
Hope that helped!
