LSAT Logical Reasoning Tips and Tricks
or…How I Learned to Stop Worrying and Love the LSAT (Part 2 of 3) In other articles, I showed you how to answer Logic Games questions and how to prepare for Reading Comprehension. This time, I’ll share the best ways to answer common Logical Reasoning questions. First, why is it possible to conquer Logical Reasoning […]
Words Indicating Sufficient / Necessary Conditions, and Time
In conditional statements (if-then) statements, the sufficient condition is the one that goes before the arrow, and the necessary condition is the one that goes after the arrow. Sufficient —> Necessary X —> Y is equivalent to: if X, then Y. X is the sufficient condition, and Y is the necessary condition. Logic Games and […]
LSAT Words: “Except” “unless” “until” and “without” mean…
I’ve talked about Sufficient and Necessary Condition indicator words before. However, I left out a couple of important words (except, unless, until, and without) that factor into conditional reasoning. These special words don’t *quite* fit the mold that the others do, so I decided to give them their own article. The words “except,” “unless,” “until,” […]
LSAT Logic | Sufficient vs Necessary Conditions
We deal with “if-then” statements all the time in everyday life. “If I have another drink or two, I won’t be able to drive safely.” “If I get a higher LSAT score, I’ll be competitive at better law schools.” The LSAT Logical Reasoning section requires us to think about these statements a little more formally […]
Arguments and Contrapositives | Necessary and Sufficient Assumptions
I spend a great deal of time talking about the difference between Necessary Assumption and Sufficient Assumption questions in my Logical Reasoning course. Arguments assume a link between the evidence and conclusion presented – this link can often easily be framed as a conditional statement. Because the contrapositive of this statement is simply a rewording of the […]
Difference Between Necessary & Sufficient Assumption Questions
Both Necessary Assumption and Sufficient Assumption questions contain the word “assumption” within the question stem. However, they ask for very different things. (Also see Sufficient Assumption Questions and the Negation Test.) This is why it’s misleading (and often confusing) to simply refer to both types under the catch-all category of “Assumption” questions. Others refer […]
Difficult LSAT Logical Reasoning Questions
Here’s a list of several Logical Reasoning questions in LSAT PrepTests that my students often ask me to explain. The number of questions listed per PrepTest/section should not be taken as an indication of the PrepTest’s/section’s overall difficulty. The questions I’ve listed are simply those that jumped out at me when flipping through each of […]
15 Common LSAT Logical Reasoning Topics
LSAT Logical Reasoning questions often fall into one of the following categories. There’s no reason to classify every LSAT question in this way. However, it’s important to be familiar with these topics and concepts so they don’t intimidate you. TV shows and violence in children Climate change, fossil fuel use, and crops Dinosaur extinction, ice […]
Sufficient Assumption Questions | Tips and Categorization
I’ve talked in another article about how Sufficient Assumption (Justify) questions are generally based in formal logic. This time, I’m going a bit further with this idea. I have analyzed every Sufficient Assumption question from LSAT PrepTests 19-58. I found the vast majority of these questions fall into one of the following 6 categories: […]
Logical Reasoning | Sufficient Assumption (Justify) Questions
Many of you dislike formal logic Logical Reasoning questions, particularly Sufficient Assumption (aka Justify) questions. In this blog post, I’ll demonstrating my technique on a few of these questions. Unfortunately, the folks at LSAC are very strict about their intellectual property and wouldn’t allow me to post their LSAT questions online, so I’m only posting […]
