Need some free GRE Math help?

This is a series of free lessons that will cover the mathematics topics required for the Quantitative Reasoning Measure of the GRE revised General Test. It is based on the Math Review text from ETS - the organization that conducts the examinations.

The topics covered are arithmetic, algebra, coordinate geometry, geometry, data analysis and tips for the GRE Examinations.

### GRE Math Practice Test Questions and Solutions

These videos will give you a quick revision for some common GRE exam style questions. Scroll down the page if you need more in-depth explanations and examples.

### Arithmetic

### Algebra

### Coordinate Geometry

### Geometry

### Data Analysis

The goal of data analysis is to understand data well enough to
describe past and present trends, predict future events with some
certainty, and thereby make better decisions. In this limited review
of data analysis, we begin with tools for describing data; follow
with tools for understanding counting and probability; review the
concepts of distributions of data, random variables, and probability
distributions; and end with examples of interpreting data.

### Tips for the GRE exam

Learn all about the structure of the test and the new question
types, get resources for additional practice and information on the
new GRE, and hear advice on how to study and prepare for the exam.
The following video provides an overview of the GRE and explains
how to make the most of your study time.
The following video gives a GRE test review. It explains what you
