Our fourth article in the GRE Quantitative Comparison series will show you another quick trick for comparing values in two columns. Let’s take a look at this problem:
Column A Column B
(221)/(400...

In previous articles (Algebra vs Plugging in and Finding Equality, we showed several strategies for approaching GRE Quantitative Comparison problems. As a refresher, the two methods are solving using algebra, or solving by plugging in...

In an earlier post, we worked through a GRE practice problem using both an algebraic method and by plugging in values for x. This post will focus on an additional strategy to use while plugging in numbers.
To get started, let’s look at...

Consider the following Quantitative Comparison question:
Column A Column B
16x + 4 4x + 16
(A) Quantity A is greater.
(B) Quantity B is greater.
(C) The two quantities are equal.
(D) The relationship cannot...

In my last post, we applied the Fundamental Counting Principle (FCP) to solve the following GRE-style question:
How many different 3-digit numbers are greater than 299 and do not contain the digits 1, 6, or 8?
(A) 180
(B) 245
(C) 291
(D)...

As I stated in my last post, the Fundamental Counting Principle (FCP) can be used to solve the majority of counting questions on the GRE.
The FCP says:
If we have a task consisting of stages, where one stage can be accomplished in A ways,...

Whenever I see a GRE resource label its counting section as “Combinations and Permutations,” a small part of me dies a little. Okay, that’s an exaggeration, but I am concerned about the misleading message that this sort of title conveys....

Average speed problems are common on the GRE. These questions can be tricky if you haven’t practiced solving them, because the most obvious answer choice is a trap. To see why, try the following problem:
Joe drives...

You’ve worked hard to prepare for the GRE, and the time is almost here. In less than 24 hours, you’ll sit down to take perhaps the most important test in your life (so far). With the test just a few hours away, what should you do now?...

Not all GRE practice questions are equal. Learn to spot substandard GRE questions so you don’t waste precious study time and energy.
