LR used to be a weak section for me (-11 to 15 per), but I've drilled so much that now the correct answers seem almost glaringly obvious to me - and when they're not obvious, the wrong answers are. It seems now I can go -3/-2 fairly easily, which has boosted my score a ton.

My best advice is to keep drilling until you know question types so well that individual questions don't matter - you'll see past whatever extraneous details/scenarios they throw your way and naturally zero in on the answer.

When I was first starting out, I found discussing questions with friends/family helped a lot because I was forced to explain why an answer was 100% right and why all other answers were 100% wrong. Articulating questions aloud also made me very mindful of word choice - the use of strongly connotative words like "always"or "never" is ~never~ an accident and almost ~always~ can help with answer selection/elimination.
