Logical Reasoning

A few general tips for Logical Reasoning:

Be familiar with the different question types

Here are links to a few good free overviews of the different question types:  http://www.foxlsat.com/thou-shalt-pay-attention-to-the-type-of-question/ http://lawschooli.com/lsat-logical-reasoning-cheat-sheet

Predict the correct answer BEFORE looking at the answer choices

If you are able to predict the correct answer before looking at the answer choices, you will be able to spend much less time on the answer choices and your odds of getting the question correct will go way up. Not all of the questions lend themselves to predicting the correct answer in advance, but a lot of them do. For example, most of the questions address an argument made in the passage. And the argument is always going to be a bad argument. It’s not enough to read the passage and say to yourself “Yeah, that’s a crappy argument, something weird is going on there”. You should be able to articulate exactly what’s wrong with the argument- that is, articulate why it is that, even if we grant that the premises offered in the argument are correct, the conclusion doesn’t NECESSARILY follow. Once you’re able to do that, there are many questions types for which you’ll be able to at least predict what the correct answer choice should look like. For flaw questions you will already have made the prediction. For weaken questions you will be looking for an answer choice that picks up on the flaw that you identified in the argument. For strengthen questions you will be looking for an answer choice that defends the argument from the flaw that you identified in the argument. And so on. This exemplifies a recurring theme across all of the sections in the LSAT: The more work you put in up front (in this case, the more work you put in figuring out what’s going on the passage and figuring out what’s wrong with the argument), the better and more quickly and confidently you’ll be able to identify the correct answer choices.
