Advice on pushing from mid-160s to 170 for August LSAT

GetaCLU-1

I've been studying for about 5 months and am taking the August LSAT. I've gone from a 156 diagnostic to solid mid-160 PTs using Mike Kim's LSAT Trainer in tandem with 7Sage explanation videos and analytics.

I recently got two scores of 168, was feeling really close to reaching my goal of 170+, but on the last two PTs I missed a lot on LR and fell back down to 165 and 163, respectively. I'm especially nervous because I had no idea that I was bombing LR and actually felt pretty confident.

Any tips for sharpening my LR in this last month push?

(I have a full-time job and am currently devoting 10-15 hours a week to studying; an expensive tutor isn't an option)

Thanks in advance!
