@. Could you properly infer that most cars are not sedans? "Some" can include "most" right (if 99/100 cars are sedans, then "some cars are sedans" and it wouldn't be proper to infer that "most cars are not sedans")? Or am I misunderstanding? Thanks.

I also drive to/from dc. I concur with what others said about going straight to the library after work. I also listened to 7sage lessons, the thinkinglsat podcasts, and other lsat related videos from YouTube in the car,and studied LR questions when I could get a few minutes here and there at work, all of which I found to be helpful.
