I think you're deciding between a once in a lifetime experience/opportunity and Law school which will always be there. If I were in your shoes, I think the choice would be pretty easy (assuming you have a love for your project).
There are also defensive driving classes you can take for point reduction ask your insurance company. If you tell lsac you took a course, maybe lsac will say to themselves " hmm, seems like she's doing her best".... Maybe...
@Alejandro and @"Cant Get Right" beat me to it! You'll do great between now and Sept hopefully. You seem to have things in common with a few of us already---You met your fellow Mississippian and now you've met a fellow history major haha :)
