I have 30 days to the test and am terrified about probability…what should I do? There is perhaps no other topic on the GRE math that instills as much dread in students as does probability. Understandably, students will obsess over this topic more than they will other topics. However, such an approach won’t only lead […]

## Mean, Median and Mode on the GRE

Over the last six months, I’ve gone through quite a few Revised GRE prep books. One thing I’ve 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, […]

## Does Order Matter? Combinations vs. the Fundamental Counting Principle on the GRE

When trying to decide whether to use the combination formula, many students have trouble applying the “does order matter” test–deciding if outcomes differ. It’s easy to say order doesn’t 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. […]

## GRE Math Challenge – Numeric Entry

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, I’ve 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 […]

## GRE Math: Solving Quantitative Comparisons

First off, here’s a tricky algebraic QC: 1) x > -3 If you find this puzzling, this article discusses an efficient method for handling such problems. Before we talk about that, a quick refresher on a few basic ideas dealing with equations and inequalities. Intro to Arithmetic Suppose you have an equation, P = Q. […]

## GRE Numeric Entry Questions

One of the most dread-inducing additions to the GRE—back when it changed in Aug. 2011—was the Numeric Entry question. The reason is apparent: instead of five answer choices to guide you, suddenly there is nothing more than a box, a big blank waiting for you to cough up one number out of millions (if not […]

## How to Approach Complicated Math Problems

Every GRE test is going to have a few math questions that are very difficult. Upon seeing them, you may become completely flustered and believe that there is no way you are able to solve such a question. Oftentimes this is not the case. Rather, you fall into any number of traps that prevent you […]

## GRE Math – Help! I’m Terrible at Math!

This is the sister post to I’m Terrible at GRE Verbal! Help! 🙂 Sometimes we all need a little GRE math help. It usually doesn’t take more than the first session for a new student/tutee to look over me and confide sheepishly, “I need help with GRE math. I’m so bad at it!” Mind you, I […]

## Quantitative Comparison Pacing Drill

The very first problem you will see test day will be a Quantitative Comparison one (QC). Indeed, the first seven problems will be QC, unless you decide to skip them (which in the case of the last couple may, for some, be a wise strategy). Therefore, while prepping, you should make sure not to neglect […]

## GRE Math Multi-subject Challenge Question

Once in a while it is fun to take a concept in an official GRE question and run with it. The question below is inspired by a question from the 2nd edition Official Guide. That is not to say it is that similar; I have only extracted a couple of concepts from that problem. I’ve […]
