Alright JY, this one is specifically for you.
I have now spent more that 24 hours watching these videos, and I'm still stumped.
Early in the videos, you said "through the miracle of Microsoft Paint" you were going to show us something.
How did you get so good at drawing accurately within paint?!?!??! Do you have one of those fancy drawing tablets? Are you not actually using paint?? Did you sell your soul for LSAT skills, and the devil threw in Paint skills as a freebee?
I keep watching these videos and trying to focus, but I'm constantly distracted by this errant thought of "How is JY doing that?"
So your answer would definitely be appreciated and help me do better while studying and on the LSAT.
Flash cards are definitely the way to go if you're trying to memorise them. Having the valid and invalid forms on index cards, and drilling them together helped me, that way I had to actually think about it rather than just look at it.
