Logic Games

Here’s a link to a free infographic with suggestions for how to diagram the most common rules that appear in the logic games section: http://www.thelsattrainer.com/diagramming-lsat-logic-games-infographic.html

If you’re having any trouble with rules involving conditional reasoning, I have made a free conditional reasoning worksheet featuring Alvin, Billie, Cinder, Django, Ella, Frank, and Gary as cats that will or won’t be adopted: ConditionalReasoningExercises

And here are the answers: AnswersforConditionalReasoningExercises

In addition, here are a few tips:

  1. If there is a general orientation question (such as “which of the following is a possible order for the cats to be adopted”) it will always be the first question. The best way to answer this type of question is by going one rule at a time and seeing which answer choices can be eliminated on the basis of the given rule.
  2. After answering the general orientation question, it is best to go out of order- do the “if” questions first, and then return later to the other questions. Since the diagrams that you draw for the “if” questions illustrate valid scenarios for the game, you can use your work from these questions to more easily and quickly arrive at the correct answers for the other questions. For example, if question #4 asks “which of the cats cannot be the 5th cat adopted”, you can take a quick look at the diagrams you’ve drawn for the “if” questions on that game to see which cats COULD be adopted 5th, and thus quickly eliminate some wrong answer choices.
  3. On the “if” questions you are always expected to make at least one deduction on the basis of the information given in the question stem. So once you read the information being given- for example, “If Gary is the second cat adopted…”- you should immediately draw a diagram next to that question, putting, say, G in the second spot, and see what has to follow. If you’ve made at least one deduction and you just don’t see anything else that follows, don’t waste your time and energy banging your head against the wall trying to come up with more deductions. Just move on to the rest of the question, and hopefully you will already have deduced what they wanted you to have deduced.
  4. Beginning with prep test 57 a new type of question has appeared in the logic games section, always at the end of a game and almost always no more than once per section. The question has the following form: “Which one of the following, if substitued for the condition that Django must be the 6th cat adopted, would have the same effect in determining the order in which the cats are adopted?” These questions are generally more difficult and more time consuming than the other questions, so if you’re not (yet) aiming for a perfect score on the logic games section, you’ll be better off just randomly guessing and moving on to the next game. Difficult questions are still only worth one point, just like every other question, so don’t miss the opportunity to get easy points on the next game because you’re trying to figure out a question that you know is probably going to be difficult and time-consuming.

5. In order to get good at the logic games you need to do a lot of them. And you need              to repeat games that you’ve already done, especially the easier games, so that you              can train your brain to recognize the typical inferences being made and the                          recurring patterns being presented in game after game. If you can get really good              and fast at the easy games (by repeating them over and over until you have really              mastered them), you’ll have that much more time to work through the more                        difficult games.
