I have been taking many of these "game" classes on line; this is the first time it actually makes sense with simple dialogue and simple building the games - I am new to the lsat journey

On the first game, I'm glad someone finally mentioned that Q wasn't in the games, but It was in the rules. It was driving me crazy the whole time! Thanks for the helpful video!

Thank you so much. I'm really glad I found this. It super helped to solidify the basics.

Thank you Ally! Your vids have really helped me a lot as someone who is just starting out on their LSAT journey.

Question on the logic game around 44:00, when they say “sleep cannot have fewer students assigned to it than metabolism” does that mean Metabolism could have an equal amount of students as sleep?

There is no actor named Quan..? I am still stumped as how "Q" can be in the rules because "Q" does not exist..! Your right Q is a typo rendering this logic game illogical says the Mr. Spock in me here Jim we could replace Quan with another name but if I get this game on the LSAT with a typo I am goin to file a lawsuit...!
