I did the LR section of the 7sage course, and am a little better at identifying the correct answer, but still don't feel like I am where I should be, is the best way to improve in LR just to spam out drills?
Take an untimed test. You'll catch your mistakes and sharpen your decision making skills. I wrote about it on a discussion post a while ago. An untimed test gave me confidence in the timed tests I took after.
