And considering the fact that everyone says Kaplan sucks, what can I do to improve my LG (already done LGB, which helped for sequencing more than grouping).  I've done 10 more and a few Next 10s.  Any suggestions would be appreciated.

I think brute force would be trying to go through a bunch of possibilities instead of think about deductions.

"Brute force" is nothing you need to worry about.  It's a bull term contrived by people who spend too much time practicing logic games.  common sense + nerd = "brute force"

No, brute force is drawing multiple diagrams that cover all the possibilities of the game.     Most will invovle drawing 5 or less diagrams that cover the entire possible outcomes.

Hah!  That doesn't even scratch the surface!

I call testing every answer choice the 'brute force' method because that's what we called it in computer science class when you have an algorithm that checks every possible outcome (of, for example, the 8-queens problem).  You want to know what's worse?  I've played around with applying forward-checking and AC3 algorithms (admittedly without much success) to the LSAT games section.  I'm nerdier that you can possibly imagine, pocus.

You're all wrong (except Trevor)... brute force is when you can't draw a general diagram and so have to figure out every question from scratch.  But we're apparently CS people... so maybe we have a different definition.

LOL!  That's too much.  You are a total nerd.  That's ok though.  I am too.

Brute force is just working out all the possibilities for each answer choice.  A lot of pencil work.

no you can draw a diagram.  Some times you can't just look at your diagram and read off the correct answer, though.  So you have to try a bunch of possibilities.  Some of the games are open-ended, so the diagram has a lot of blank space in it.  You always start with the diagram and then start working out all the possibilities.
