Personally I was horrible at LG but managed to reach -1/0 when I started intentionally drilling the hardest LGs in LSAT history (I just searched up "7sage logic games explanation" and would track down all the games that were marked as 4 stars). I would initially do the game untimed (of course noting however long it took me). After my initial attempt, I would then check my score and then watch a 7sage video on the game to see how they did it more efficiently/accurately. I would then go back to the game and redo it until I finished it in under whatever recommended time 7sage says. I would note the game, and then redo it the next morning once more to have the patterns reinforced.
LG is essentially just a matter of repetition, but honest repetition (by that I mean it should be done with the intent to improve your efficiency in making a clear diagram and looking for must be true inferences)! The more you do LG, the more comfortable you get with making quick inferences - which in turn translates to faster LG sections.
Thanks for being so honest. I was thinking that I could manage 1L being online (well, that's what I tell myself), but I really am hoping for an in person 2L experience. I want to be able to moot and make the most of this experience.
