If I were you, I'd take a year. Get a job--a real job, mind you--and get some work experience doing what you learned in undergrad. Also take that time to reflect on why you want to go to law school, and more to the point, why you want to be a lawyer. If you're still feeling that itch, you can study for the LSAT and try it again, this time with a few entries on your resume to help you along.
