LSAT 79 Explanations

LG Game 3 Setup, by LSATHacks

Game Setup

Time on first attempt: 6:56

—————

This is a three group grouping game. You can draw it like this:

LSAT Preptest 79, Game 3 Setup, Diagram 1

I added rule 1 directly to the diagram: Markets must have exactly two assistants. The line to the right shows that the group is full. This is important – it means that the other two groups either have 3 and 1, or 2 and 2. (Each groups needs at least one assistant)

I drew rule 4 next, because it create a dual possibility: either Y and Z are in pricing, or they both can’t go there:

I also added rule 3 to the left hand scenario: Z and V can’t be together. You should also draw this separately in your list of rules:

The final rule is that T and S must go together. You can draw it like this:

You can’t draw this TS rule on the diagram, but….you should know that often a question will close off one of the three groups. This makes it much harder to place both TS (which must be together) and VZ (which can’t be together). When doing a three group grouping game, you should always keep this in mind – the questions are designed to have big effects when one group is closed off.

Finally, you should note that R is random:

    Rule 3 said that VY can’t be together, not VZ.

      Agreed. Please fix. It’s also incorrect in your guide.

    Why can Z and V not be in the same course? it is V and Y in the rules that it says

    Hey! Just a note: the third rule above should be that V cannot be with Y, not Z. Its correct in the problems. Thanks so much for these breakdowns, they are very helpful!
