Thanks again everyone for taking the time to respond to my inquiry. This is great advice. I am going to target the 11/17 exam.

Thanks all, much appreciated. Thus far, all responses point to the September LSAT considering my full-time employment status, timeline, goal, and the fact that I scored in the 140's on a true, timed diagnostic.
