Here’s an easy way to pick up an extra point or two on your LSAT score (or 10 or 20 on your GMAT score): When you’re reading logical reading questions, pay close attention to the qualifiers attached to the statements they make.
Simple little words like “some,” “many,” “most,” “few,” “all,” “maybe,” “probably,” “often,” “usually,” and so forth may seem interchangeable and are easily overlooked, but in fact any qualifier can critically change the meaning of a statement in which it appears. Furthermore, because the test writers know that these little words are so often overlooked, qualifiers are a favorite trick to lead unwary test-takers astray.

Today’s question comes from the GMAT. It’s Critical Reasoning Practice Question #7 in The Official Guide for GMAT Verbal Review, 2nd Edition (page 118).
A researcher discovered that people who have low levels of immune-system activity tend to score much lower on tests of mental health than do people with normal or high immune-system activity. The researcher concluded from this experiment that the immune system protects against mental illness as well as against physical disease.
The researcher’s conclusion depends on which of the following assumptions?

Today I’m posting the first installment of a new occasional series for this blog. In each Reference Sheet, I’ll cover, as succinctly as possible, every rule you absolutely must know to solve problems in a single area found on standardized tests.
Learning these rules isn’t a substitute for developing higher-order problem-solving and strategic thinking skills; rather, it’s a necessary precondition and foundation for all of that strategizing to take place. This Reference Sheet lists the minimum requirements to get your foot in the door. It’s the price of admission.
If you’re taking any test involving exponents, here’s what you need to know:

A couple of weeks ago I did an LSAT reading comprehension passage, but I threw my timing off by taking notes for my blog post as I worked. I’m going to try it again with a new passage, but this time I’m going to treat it exactly as I would on the actual LSAT — and skip the notes. We’ll see if my time improves — and whether I maintain accuracy in the process.
Alright, let’s get to it! I’m doing PrepTest 60, Section 4, Questions 1-7 (10 New LSAT, page 316-317). There are 7 questions here, so our target time is around 9 minutes. See you in 9 minutes!

I recently ran across a fascinating article about test prep that I’d like to share:
http://psychcentral.com/news/2012/08/24/prep-for-law-school-admission-test-alters-brain/43665.html
A somewhat more-detailed version from Berkeley itself:
http://newscenter.berkeley.edu/2012/08/22/intense-prep-for-law-school-admissions-test-alters-brain-structure/
The full study is here:
http://www.frontiersin.org/Neuroanatomy/10.3389/fnana.2012.00032/full
TL;DR: LSAT preparation structurally alters students’ brains in ways that seem to fundamentally improve reasoning, learning, cognition, and perhaps even IQ.

Let’s do some reading comprehension!
To make this as authentic as possible, I’ll pick a passage I haven’t seen before, time myself, and try to comment on my thought process as I go. Okay? Good. Reading comprehension is a staple on pretty much every major standardized test, but I’ll be doing one from the LSAT: PrepTest 57, Section 4, Questions 6-12 (10 New LSAT, page 210-211). Here we go!

I’ll endeavor to keep this tractate laconic, for reasons that will become manifest forthwith.
I’ve had myriad SAT and GRE abecedarians ask me the best modi for augmenting their vocabularies in order to meliorate their sentence completion scores. Other students, signally nonnative speakers, yen to bolster their lexicons in order to wax their reading comprehension aptitudes.

Building off the formal logic posts of the last two weeks, today we’re going to discuss the LSAT logic game found at PrepTest 58, Section 3, Questions 7-12 (10 New LSAT, page 241).
This is a fairly simple In-and-Out game (also known as a Selection game). Such games often involve heavy doses of arrow diagramming, and this one is no exception. Take a quick read of the setup and then let’s turn our attention to the rules.
The rules of this game can be diagrammed in straightforward fashion as follows:
1. R→M
2. M→T
3. !S→V
4. !R→L
5. T→(!F and !V)
Let’s turn to the questions now.

Last time, on Formal Logic:
* We learned that formal logic is an important part of the LSAT.
* Arguments were broken down into propositions, which were shorthanded by capital letters and manipulated using operators.
* Finally, negation and arrow diagrams burst onto the scene, leading to a shocking revelation: A→B says nothing about what happens in the “not A” case!
But what other arrow diagram is equivalent to A→B? How can arrow diagrams be combined? Will we ever finally see an LSAT question example? Does Anthony have his umbrella?
These questions and more will be answered… tonight.

The facts are the least important part of the LSAT.
It’s one of my favorite refrains, because it challenges students to rethink their approaches to the test and create real change in their results. And sure, it’s a slight exaggeration — the facts do matter, at least in some ways — but it’s more true than you might think. A successful approach to the LSAT starts with consideration of logical structure and runs through qualifiers, connecting words, and question types before ever arriving at the sort of fact-based considerations by which too many test takers live and die.
