Originally had my heart set on NYU, but that's clearly out of the picture with these numbers.

Also: WUSTL?
Underperformed on October LSAT - had anticipated ~168. Is it possible to get to 170+ by December, and how greatly would that improve my chances at T14 schools? Also, for NYU, would I need to aim for an average of 170-172, or would it be enough to hit that score on the retake (i.e., average ~168)?
Lastly, how would a December retake influence my competitiveness this cycle? Would it be better to retake at a later date and apply to schools next fall?
Not sure if this would make a difference in admissions, but I wanted to give a bit of context concerning my GPA: Currently low from starting uni as pre-med and getting a few Bs in science courses. Since then, have had 3.85+ each semester (consistently increasing) with 4.0 last spring and am anticipating ~3.8 at time of graduation. Non-science GPA is 3.9+ (not sure of the exact number off the top of my head) and GPA in major area (poli-sci) is 3.88.
ETA: I don't necessarily expect one person to answer all of my questions (but, if you are so inclined, please feel free to do so). If you have an opinion about my chances at a particular school or on some other specific part of my post, I'd love to hear it! Any and all advice would be helpful. <3 Thanks!
