LSAT PrepTest 84, Section IV, Logic Game 3 Setup

Game Setup

Time on second attempt: 6:16

See “repeating games” at bottom of section

This is a grouping game. I found it fairly standard. It becomes fairly easy if you make dual scenarios. I’ll show you how to do that.

The third rule is what lets you make split scenarios. Either F is the nominee for treasurer, or H is. You should draw both scenarios:

I’ve added the first rule to the left hand scenario: if F is in, G must be out.

I’ve also added the fourth rule to the diagram. K can’t be councillor. Now, you could just leave it at that. But if you look closely, there’s another deduction. In either scenario F or T fill up the spot of treasurer. Which means that K can’t go there either. You should draw that:

So, if K is in, they must be mayor! All that’s left is to draw the remaining rules:

FG can’t go together (rule 1). If H is councillor, then J must be mayor (rule 2). And finally, L is random, which I’ve indicated with a circle.

I also drew K there, mostly as a visual reminder. Since F, G, H, J and L were already in the list, I preferred to draw the 6th character so I could count them. But, note that K can only be mayor, so they’re not totally unrestricted like L. (You could equally leave K out of this list)

That’s all there is to the setup!

Repeating Games

I’ve written elsewhere about the benefits of repeating games, to solidify your intuition for deductions. Note that the purpose of repeating games is to prove the answers right, so it doesn’t matter if you remember the right answer.

I repeated this game about three days after I first saw it, by which time I had forgotten the answers. I’ve written how long it took me on the second attempt. That time, or a couple minutes above it, is roughly the standard you should be aspiring to — a lot of people take 8-9 minutes on a repeat attempt, get everything right, and pat themselves on the back. But that’s too slow. The faster you go when repeating, the faster you’ll learn to go the first time you see a game.

(I say “a couple minutes above” my time because, after years of teaching the LSAT, I’m really, really fast. You should be almost as fast as me, but you don’t exactly need to match my pace to score -0.)
