Want to focus on harder ones so I'm not surprised on test day. I have access to all of them and have taken 82, 81, 79, 78, 76, 70, 69, 66, 54, 18, 17, and J07 (and I took PT 89 when it was a real LSAT administration). Particularly want to challenge myself on Logic Games (my weakest section) but other hard sections are good too. All advice welcome!
