What is logical reasoning?

Logical Reasoning makes up two of the three scored sections of the LSAT.

Each question gives a short argument or set of facts and asks you to analyze it: find the flaw, strengthen or weaken the argument, pick the assumption, or draw the conclusion that follows.

The section tests careful reading under time pressure more than any special subject knowledge.

Because it is two-thirds of the scored test, LR improvement moves your score more than anything else.
