During this summer, I did 3 games of almost every LG. Taking the LSAT in Oct, I've started up prep. I've been doing the basic linear games. I can't seem to do them as quickly as I could before (5-6 mins/game). Now I do them slower (7-8 mins) and with some careless mistakes. For example, this one easy game took me 12 minutes for some reason, and I didn't get all the questions right. However, after dinner I did the questions before I reviewed them, and they were so easy. Does it take some time getting back into the hang of things again?
When I cracked open the LG Bible again for the first time a couple days ago, I bombed the easiest most basic linear game. After a little more review of concepts though, I've been conquering the rest of the basic linear games AND advanced linear games no problem, more quickly and with fewer mistakes than I did the first time around (several months ago). You'll get there; don't get discouraged.
