Here are ten GRE math practice questions to get you ready for Quantitative Comparison.Ā All of these can and should be done without a calculator. Solutions will come at the end of this article. 1) 2) The number n is an integer greater than 2 3) The number x satisfies the restriction 4) 5) Set S […]

Today, weāll quickly look at how a rectangle and parallelogram can have the same area. In the diagram to the above, the parallelogram and rectangle share a vertex (D), one vertex of the rectangle (E) is on a side of the parallelogram, and one vertex of the parallelogram (C) is on a side of the […]

Over the last six months, Iāve gone through quite a few Revised GRE prep books. One thing Iāve noticed missing is difficult questions relating to mean, median, and mode. Sure, most books describe how to find the average, and what the difference between the mean and the median. Many already know the above, but mean, […]

This may come as a surprise, but there is more than one way to classify an exterior angle. You will want to have both of these definitions in mind when dealing with questions on the test since both instances are possible. Don’t worry! It won’t be too difficult to remember. Type I: At each vertex, […]

Today, weāll cover special quadrilaterals and the facts that you should know. These will allow you to answer questions quickly and understand the basic nature of these shapes. 1) A Typical Parallelogram All parallelograms have the BIG FOUR properties: 1. Opposite sides are parallelāAB // CD, AD // BC 2. Opposite angles are congruentāā BAD […]

When trying to decide whether to use the combination formula, many students have trouble applying the “does order matter” test–deciding if outcomes differ. Itās easy to say order doesnāt matter when it in fact does, and vice versa. Once you get it, it’s really useful, but it can take a bit of thinking and re-thinking. […]

Below are some tough word problems that require both close reading and sharp problem solving skills. To make these already difficult questions even more fiendish, Iāve made each a Numeric Entry question (sorry, no cool boxes). In some of the questions below, there are a few possible solution paths, some more elegant than others. If […]

A relatively common exponent question on the GRE will ask you to figure out the units digit of some number raised to an exponent, which usually results in a number roughly equivalent to the number of grains of sand in the Sahara, and thus out of reach of the GRE calculator. Take a look at […]

Suppose you have been away from math for a while, perhaps since Algebra Two and the SAT in high school.Ā After these necessarily evils, you bid it a hasty farewell and gave it the bum’s rush from your entire life.Ā Now, several years later, you have completed a Baccalaureate degree in something, and wish to […]
