Need some advice. I scored a 164 on the LSAT. The school I'm applying to a school that has a median LSAT of 161 and a 3.8 GPA, while I have a 3.7 GPA from a less well-known school. I'm considering retaking the LSAT to try for a higher score since i really want a full ride, im considering retaking it. About 18% of admitted students receive full scholarships in this school. Do you guys think it's worth retaking?

If I get -1, or -0 frequently on old LR sections that i have taken a month or 2 ago. Is that a good sign?
