Buy the book “The Loophole in LSAT Logical Reasoning” by EllenCassidy. Aside from 7Sage Ultimate+ it’s been the single biggest score booster for me. If you struggle with LR you need the Loophole.
Give “The Loophole in Logical Reasoning” by EllenCassidy a read if you haven’t already. LR and RC were my naturally strong sections, but that book augmented my performance and allowed me to keep my LR sections to -1 or -0.
