# Complete GRE Math Concept List

**How To Study For GRE Math**

**Welcome, stranger. **

If you need to take the GRE, but you hate or fear math, this guide is for you. We're going to start at the very beginning and build from there.

Note: The main reason I made this page is that although ETS (which creates the GRE) has published its own guide to learning GRE math on Khan Academy, ETS's guide to Khan is riddled with inaccuracies and is difficult to use. Mine isn't perfect, but it's way better.

To skip straight to my guide, just scroll to the bottom of this article.

## What Kind Of Math Is On The GRE?

**The GRE has a brief - very brief - review of all the math concepts it tests in its free** **Math Review**. Stop reading and click on it. The Math Review tells us what's on the test. In a nutshell, arithmetic, algebra, geometry, and "data analysis" - which means statistics and probability.

**Now, mark which concepts you know and which ones you might not or don't know. **Use the Math Review to try to learn ones you don't know. This means read about the concepts and do all the practice exercises at the end of each section.

However, you may very well need much more practice than the ETS Math Review can give you. For example, for certain concepts, you might just need a reminder - like for a certain exponent rule. For other concepts - perhaps probability - you may feel like you need much more depth.

That's where Khan Academy comes in.

Here's a pic from the **Khan Academy website** to show you where the video lesson, written lesson, and practice questions are for each concept - and where you can take a quiz or test to gauge your skills.

**FYI, understanding the video does NOT mean you can do the problem from scratch.** So, make sure you take advantage of the practice exercises as well.

**Pro tip:** If you're not sure whether you are good with a particular concept, try the quizzes or even the unit test.

## GRE Math Practice Questions

Once you've mastered a concept, check it off on the ETS Math Review and move onto the next one. **Your job is to get this whole project done ASAP**, so you can start practicing with more realistic GRE math questions. The more math questions you successfully solve on your own - i.e., without following someone else's solution - the better you get.

**It's a numbers game, pun intended.**

Important: having a plan and schedule is crucial. Make sure you check out my **1, 2, 3, and 4-month GRE study plans**.

Spoiler: All my plans involve heavy use of the Manhattan GRE 5-lb. GRE practice book, and most importantly, official ETS GRE practice questions. This is the big reason they're better than plans from companies like Magoosh, whose plans will have you wading through hundreds of unrealistic Magoosh-written questions.

**A common myth** is that practicing with "harder" questions than you'll see on the GRE will make the real GRE seem easier. This isn't true, because those "hard" questions - if they're written by test-prep companies like Magoosh, Kaplan, or the like - will be hard for the wrong reasons - unrealistically computation-heavy, obscure, or written with no possibility of a shortcut. This is why we want to eventually do as many real ETS questions as we can.

## The Most Important GRE Math Tip

It's important for you to know that being able to solve math questions on the real GRE is a skill that comes from practice with real GRE questions. Shocking, right?

Real GRE questions are hard until they're easy. By that, I mean that they're often wordy and complicated but often can be solved by cutting through the words to figure out what the question's asking, or by using a logical shortcut. They're testing your ability to think with math skills - which is why the section is called "Quantitative Reasoning".

This means that memorizing formulas, reviewing notes, or watching math videos are WAY less important than getting your hands dirty by doing a ton of ETS math questions by yourself - then keeping a detailed mistake journal (as described in my study plans).

## A Few More Things About Khan Academy

**Important note:** If you see a concept in the ETS Math Review that you don't know but can't find it on the Khan page I've linked to, **type it into the Khan Academy search bar**.

BUT if you find a concept in Khan that is NOT in the ETS Math Review, don't worry about it. **I'll list anything you DON'T need in Khan next to each Khan link.**

**Concepts you DON'T need to know** that are in the ETS Math Review: how to calculate standard deviation.

## Can You Use A Calculator On The GRE?

Yes! It's an on-screen calculator that you can use at any time during a GRE quantitative section.

Your GRE calculator can add, subtract, multiply, divide, and square root. But that's pretty much it. And the display only fits 8 digits.

(just like a calculator from the '80s!)

**Pro tip:** download a GRE calculator app onto your phone when practicing GRE math, since your phone's calculator is actually much better than the GRE calculator...

The test center at which you take the GRE will also provide you with scrap paper and a pencil. So practice using a pencil, not a pen.
