I find the 7Sage proctor app pretty funny when you turned distracts and background noise to level 10. It sounds like I'm taking the LSAT in a hospital TB ward rather than a university lecture hall!
I second what Amanda is saying, background is key. You can also try checking out an Art History book from the library. I read something like Art History of the 19th Century when I was having similar problems. Took the mystery out of it for me.
LSAC rates the difficulty of every question in the SuperPrep book, so you can look to that book if you want to start putting together a general idea. To my knowledge there are no official difficulty ratings for any other published question.
Just gain some confidence in your ability. You obviously know what you're doing :) just say. Ok LG I'm going to f&^* you up. And persist! You can do it, you have all the knowledge!!
I know you're excited for gatherings in other areas, so am I! We just don't have any planned right now (to my knowledge). If any come up, don't worry, I'll post them on the forums like I did here!
