GRE Math for People Who Hate Math: What Is a Variable, Really?

Imagine a world where every conversation went like this:
Student: When is our final project due?
Professor: Three days after the first Wednesday after your rough draft is due.
Student: What?
Professor: The rough draft is due 15 days after the date 6 days before May 14.
Solving a GRE math word problem is a little bit like having this kind of conversation. That’s why word problems can be so infuriating. The problem isn’t lying to you. It’s just telling you the truth in a really annoying, backwards way. (Reading Comprehension problems do that too—it’s not just a Quant thing.)
In the conversation above, how would you work out the due date of the final project? Personally, I’d start by getting out my calendar. I’d start at May 14, then count 6 days backwards. Then, I’d count 15 days forwards, put a star on the calendar, and mark it ‘rough draft.’ Then I’d find the first Wednesday after that date, and finally, I’d count three days forward from there. That would give me my answer. Read more
Solving GRE Problems in Multiple Ways to Build Flexibility
Did you know that you can attend the first session of any of our online or in-person GRE courses absolutely free? We’re not kidding! Check out our upcoming courses here.
Recently, my colleague Tom and I decided that, since we were teaching in adjacent classrooms, it might be fun to combine our classes and co-teach a lesson. Tom and I have very different strengths, both as test-takers and teachers. I love algebra, and I’ll always seek out an algebraic solution to a problem (even when this might not be the most efficient method—my strength is also a weakness). Tom prefers non-algebraic methods, like drawing diagrams or picking numbers. And our strengths inform what we emphasize in class.
So, for our joint lesson, we chose a number of GRE problems that could be solved in more than one way, and then took turns demonstrating each method. First, we each used the method we preferred (algebra for me, picking numbers for Tom), and then we switched and demonstrated the method we were less comfortable with. Here’s one of the GRE problems we used: Read more
Look Before You Leap When Studying for the GRE

People study for the GRE in different ways. Some people spread their studying out over time, taking 10-15 minutes every few days and studying for several months or more. Others condense their studying into a more limited amount of time.
When I was first studying for the GRE, I was lucky enough to get to doing it during six weeks I had off over a summer. During this time, I mainly spent my time doing two things: learning vocabulary (using flashcards) and taking practice tests.
I spent so much time studying for the GRE during this time that I began to have dreams about exponents, ratios, and number properties! Sometimes they were nightmares, in which I imagined myself confronted with an unsolvable problem, filled with a growing sense of dread as the clock counted down to 0.
Other times, however, I had dreams that filled me with a sense of confidence. In these dreams, I was confronted with a problem, and, even before I knew what the answer to the problem was, I knew something even more important: I understood what the problem was asking me to show. Read more
GRE Sentence Equivalence: Theme Traps
You can attend the first session of any of our online or in-person GRE courses absolutely free. Crazy, right? Check out our upcoming courses here.
There are four reasons to miss a GRE Sentence Equivalence problem. Here are three of them:
- You misread the sentence.
- You didn’t know all of the vocabulary words (or remembered a word incorrectly).
- You were short on time and the problem looked tough, so you guessed and got unlucky.
These are all things that you can address with practice. (Check out our Text Completion & Sentence Equivalence Strategy Guide for ideas!) However, we won’t be talking about them here. Instead, let’s look at a fourth reason to miss a GRE Sentence Equivalence problem:
- You fell for a trap.
GRE Percent Change Questions
Did you know that you can attend the first session of any of our online or in-person GRE courses absolutely free? We’re not kidding! Check out our upcoming courses here.
One of the most common mistakes many students make on the Quant section of the GRE is to misread percent questions, especially ones that ask you to calculate percent change (i.e. increase, decrease, more, less, greater, discount, or profit). You can fix this issue with a bit of practice, but it requires some careful reading on your part. Read more
How to Really Remember a GRE Vocabulary Word
You can attend the first session of any of our online or in-person GRE courses absolutely free. Crazy, right? Check out our upcoming courses here.
Think about your least favorite GRE vocabulary word. You know the one—every time you see it in your flashcards, you get that sinking feeling of dread. You always get this one wrong. You know it’s important, but for some reason, it just won’t stick in your head.
Okay, do you have a word in mind? Let’s conquer it—right here and now. Read more
GRE Prime Factorization and Divisibility Problems
Did you know that you can attend the first session of any of our online or in-person GRE courses absolutely free? We’re not kidding! Check out our upcoming courses here.
Here’s a hard problem that I used to teach in session 1 of our GRE course (my poor students! This was a rough intro to GRE math.)
If you’d like to, give yourself a minute or two to try this (but don’t bang your head against it for too long). If you’re thinking wow, I have no idea what’s going on here—well, it’s a good thing you’re reading this. And even if you do feel comfortable with this problem, it might be worth reading further to see how the techniques used to solve this are more broadly applicable in GRE Quant. Read more
How to Hack GRE Reading Comprehension: Think Like a Lawyer!
Did you know that you can attend the first session of any of our online or in-person GRE courses absolutely free? We’re not kidding! Check out our upcoming courses here.
After working with thousands of students, I’ll admit: Reading Comprehension is my least favorite subject to teach. Why? Because unlike Quant, it doesn’t have concrete rules to apply, so it can be harder to find ways to help when students are struggling.
I have found, though, that many students who struggle with GRE Reading Comprehension aren’t actually struggling with the “reading” or the “comprehension” part (unless they struggle with English skills generally). No, the passages – though dense and often boring – are mostly ok. It’s answering the questions that’s a struggle!
RC questions can seem vague, and the answer choices can feel like a sphinx’s riddle. Often 2 or 3 answers choices may seem equally right, or maybe none of them seem right! So what should you do? Read more
How Much Do I Have to Learn to Beat the GRE?
Did you know that you can attend the first session of any of our online or in-person GRE courses absolutely free? We’re not kidding! Check out our upcoming courses here.
Not as much as you might think. However, it’ll still take time, hard work, and a change in mindset. A lot of the learning you have to do to beat the GRE won’t look like what you’re used to. Sure, you’ll spend some time reading books and taking notes. But you’ll also need to study and think in ways that go against what you may have learned in school.
The GRE isn’t a perfect test. For instance, the research is split on whether it predicts how well you’ll do in graduate school. However, people who say that the GRE “doesn’t test anything” or “only tests how well you take tests” aren’t quite right, either. There are certain skills that, if developed, will consistently help you do well on the GRE. And these skills are learnable. One of them is the ability to use your content knowledge under pressure.

I Have a Perfect GRE Score, and My Cousin Just Asked Me How to Prep for the Test. Here’s What I Told Him.
I got an email from my cousin the other day—he told me that he’s interested in taking the GRE. Since I’m a GRE instructor with a perfect score on the test, he’d come to the right place. He wanted to know the basics: what first steps should he take? How much should he prep? How does the GRE even work? I gave him some pretty comprehensive advice, and my cousin found it so useful that I wanted to share it with you all. Read on below.
What is the GRE?
So, the GRE (Graduate Record Examination) is administered by ETS (Educational Testing Service), the same organization that administers the TOEFL and some other exams. The GRE is used by a lot of master’s programs, mostly in the sciences and humanities but also more recently for business school as well. It’s worth reading the overview here and here. While it costs $205 each time, I recommend planning to take the exam at least twice. Read more
