OH serious recommendation! Sudoku is great for keeping the logical brain up while doing something not specifically LSAT-related. It's a really similar pattern of reasoning. I think it helps me a lot especially with sequencing games.
I agree! You def still have a shot at USC! A 169 is past their 75 percentile, you just have to make sure all your essays, recommendation letters and resume are spot on.
Congratulations on that huge improvement! I'm so excited for you :)
