Logic Games - Making Difficult Inferences vs Jumping into Questions

Postby mysonx3 » Tue Aug 13, 2019 11:51 pm

I've been working through the PowerScore Logic Games Bible, and I'm noticing that there are times when they make some rather difficult inferences where their explanation seems to be along the lines of "if you place variable X in this spot, you can place variable Y in either this spot or this spot. If you do the former, there's no room for such and such, and if you do the latter, there's no room for such and such". I would give specific examples, but I'm not sure if maybe that would be bad since it might "spoil" the logic game for someone who might be using it in a practice test later.

Basically, my question is - should I be focusing on learning to make difficult inferences during setup, or should I make the "easier" inferences and jump into the questions and hope things fall into place? I know a lot of this depends on just how difficult the inferences are, so I wish I could provide a better explanation of the type of inference I'm talking about. I'm getting almost all of the core/basic inferences already.

Depends on you. When I first started studying I would always try to "solve" the game right out of the gate, hoping to find all the inferences and answer every question in a hot sec. Then I got a tutor and told me to just set up a simple board, put the pieces in place and jump right in to it. I brute forced every question, and if I found an inference along the way, I added it to my main board. If you can get fast enough at the plug an chug, it's a more sure-fire way to make sure you've got the right answer (because you've worked through many possibilities). This is not the TCR though. It worked for me (consistent 0/-1 by the time I was done) but might not work for everyone.

You should always look to combine rules that can be combined. That doesn't require making a sketch, but LSAC expects higher level test takers to be able to make those inferences and designs questions to throw free points at those that do.

It may help to know why the logic games section is there, and what LSAC is trying to test for. In law school and practice, you'll often have a general rule but an exception or defense that comes up in specific cases. You're going to be expected to balance multiple rules and see how they fit in with each other. That's why at a basic level if you have a rule that says A before B and another that says B before C, you will almost always have a question about the earliest C could go or latest A could go.

At the end of the day, you are going to have to combine rules at some point - either before the questions or on a question. It makes more sense to do it upfront because then you can use that information on every question, not only the one that's specifically testing for your ability to combine rules.

Regarding setting up master sketches or multiple master sketches based around where you place one variable, this is a game specific inquiry. There's no uniformly correct approach. Sometimes it's extremely helpful, sometimes it's a waste of time. You need to develop sufficient proficiency to be able to make that call at the line of scrimmage. As a general rule of thumb, straight distribution games tend to be the most successiptible to being reducible to a few sketches.
