Game 3: September 2009 LSAT, PrepTest 58 Section 3

If you're looking for free interactive explanations for LSAT logic games, you've come to the right place.

This game is from PrepTest 58, which was administered in September 2009. The pencast form is pretty good for showing how a 180 LSAT test-taker attacks the logic games section and has 15 minutes to spare.

Questions 13-17 make up an interesting sequencing game because it utilizes a lot of barriers keyed to a supergroup and subgroup. Barriers dramatically limit the permutations in a game, but are difficult for many people to draw cleanly into their diagram; this game is a perfect chance to practice how to visually lock in more complex sequential interactions.

The general task is to order planes--P, Q, R, S, T--into subgroups of domestic and international flights, while taking into account the supergroups of two different companies, Flyhigh and Getaway. There are, of course, some rules governing which type of flight a given plane makes, but all the sequencing rules are contingent on assignment rules.


No wonder flights rarely take off on time. If your diagram looks like this, email so we can schedule some online LSAT tutoring.
