The Basics of the GRE

If you’re wondering what the heck the GRE is and why you would want to suffer through it, you’re in the right place.

Start with our guide on What is the GRE? to understand the fundamentals of the GRE exam. If you think you have a silly “rookie question” about the GRE, we’ve probably answered it in one of our articles.

Let’s begin with the Quant section.

Welcome to GRE Quant

A very different kind of math problem solving.

The GRE Quantitative Reasoning section consists of 27 questions, split across two sections. These GRE quant sections feature two main question types: Problem Solving and Quantitative Comparisons. After you finish the GRE, you’ll receive a quant section score on a scale from 130 to 170. Your quant score will also be added to your Verbal Reasoning score to produce your overall GRE composite score, on a scale from 260 to 340.

Before the content comes the mindset. Charles shows you how GRE quant rewards decisions over calculations, and how to stop the section from dictating your pace.
