The Logical Reasoning portion of the LSAT accounts for half of your total score. Thus, you can see why it is important to have a good handle on this section! However, many people find this section to also be the hardest. Let me tell you a little about what to expect from logical reasoning and hopefully you will feel a more confident attacking these questions.
The logical reasoning questions are designed to test your ability to analyze, evaluate, and complete arguments. There are roughly 25 questions per logical reasoning section. As with every LSAT section, you have 35 minutes to complete the section. Each logical reasoning question in structured in there parts: the question, the passage, and the possible answers.
You should always start logical reasoning questions by reading the question first. The question will let you know what to look for in the passage, from pointing out flaws in the reasoning to assumptions that the author makes. The questions could also ask you, among other things, to strengthen or weaken the argument, identify the main conclusion, infer facts from the passage, or parallel the reasoning. There are roughly 15 different question types that are commonly asked in these sections. With some practice you will be able to identify each question type, and hopefully learn some tricks and tips to attack those types of questions.
The next step in answering a logical reasoning question is to read the passage. This short passage is usually 3-4 sentences long and on any topic for biology to art. It is not important that you have any background on the topics of the passages, in fact previous knowledge can actually confuse you sometimes, but rather that you can critically examine each argument. These passages are typically composed of 2-3 premise sentences and a conclusion sentence (the conclusion is not necessarily the last sentence however). When you are practicing, and taking, the LSAT, one key trick is to take a few seconds to identify what role the different sentences play in the passage.
Finally comes the list of possible answers. There will be 5 possible answer choices. The best way to attack the answers is to try and eliminate the four wrong answers, rather than picking the one answer that you think is correct. Just as with the reading comprehension section, make sure to read all of the answers every time.
While the logical reasoning questions can seem intimidating at first, if only due to the variety of skills that they test, with practice you will be able to identify the question type, how you should approach it, and common right and wrong answers.
