## How Many Geometry Questions are on the GRE?

For the GRE Quant, you definitely need to know your geometry. But just how much should you be fretting about triangles, circles, and the like? Well don’t expect half of the questions in the math section to be geometry based. The real number is a little less than ten out of forty – though, depending [...]

## QC “Who Cut the Cheese” GRE Challenge Question

This one is a real toughie. It is probably more difficult than any quantitative comparison question you’ll see test day. See if you can crack it under 3 minutes. A cube of cheese is 3-inches high. The cheese is sliced twice. Column A Column B Resulting surface area of all the slices of cheese 90 [...]

## GRE Geometry Diagram Assumptions

What can you assume on GRE geometry diagrams, and what can’t you assume?  First, here are a couple of practice questions. 1) Quadrilateral ABCD is a rectangle. 2)   What you can’t assume on GRE geometry problems The biggie is: no diagram is drawn to scale.  That means — if nothing is specified about the [...]

## Advanced Math: GRE Geometry Challenge Question

Triangle ABC is symmetric about the y-axis. Point A is located at (-4,0), and AB is the longest side of ABC. If the perimeter of ABC is 18, what is the area? 3√2 6 6√2 12 24 Step #1 With coordinate geometry questions in which there is no coordinate plane, always make sure to draw [...]

## 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 [...]

## Breakdown of the Most Commonly Tested GRE Quant Concepts

The 2nd edition Official Guide has just been released. At the back of the book is a new test (GRE Practice Test 2). In general, the concept break down is not surprising, if you look at the concepts that pop up in Practice Test 1 (which is the same as the practice test in the [...]

## GRE Coordinate Geometry Shortcut: No Graphs!

For many, coordinate geometry is already a daunting concept. When a question dispenses with the graph all together, students can feel even more at a loss. If you fall into this group, do not despair. Here is a helpful guideline:   Do Not Always Draw the Graph This advice may seem counterintuitive. After all, the [...]

## GRE Geometry Formulas

Perhaps you recall with more than a little dread your high school geometry class: fifteen-step proofs and the law of cosines were two things you were certain you’d never see again. Well, if you are taking the GRE, you were by no means mistaken—proofs and indeed all of trig are nowhere to be found on [...]

## Will there be Parabolas on the GRE?

Probably not. Meaning that parabolas can show up on the GRE, but probably won’t show up on the GRE you are taking. That is my initial take based on forums and students experiences. Still, parabolas, along with absolute value graphs, are included in the Practicing to Take the Revised GRE book. ETS obviously didn’t put [...]
