note: if you have to retake, you will apply mid-cycle. For some schools this is fine, for others this will make your chances significantly worse. Check LSD graphs of LSAT vs application date for the schools you're interested in.

You will get your score with plenty of time to apply this upcoming cycle. Scores come out about 3-4 weeks after the test date. You could even submit in September, but it would be easier to apply in October so that you have time to write quality personal statements (the admit advantage for September applicants vs October is negligible at best).
