Depending on what schools you want, it will either be too late or not. If I were you I would make a list of schools you plan to apply to, then check the last LSAT they take and their application deadline.

I think though that if you are above the schools average LSAT score and you apply a bit later, it won't hurt you. Especially considering (I am assuming) you likely have quite a bit of work experience since you have been out of college for awhile. Better to give yourself time to study and achieve a high score instead of rushing to write and getting a lower score. Good luck!
