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
Why College Is a Great Time to Prep for the GRE
Undergrads get our best prices on classes, up to $400 off. Click here to find out how!
If you’re in college, graduate school might sound like a faraway, almost ominous concept. Do you have a dream grad school that you want to attend one day? Do you know what it takes to get into a top grad school? Have you heard about the GRE, or Graduate Record Examination?
It can definitely be an overwhelming experience, but it doesn’t have to be. If you give yourself enough time to prep the right way, the test starts feeling less scary and easier to understand. You’ll stop breaking into a sweat at the sight of an exponent or a sentence with five commas, and you’ll feel your confidence building. 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
Grad School Admissions Committee: The View from the Inside
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.
I have been fortunate enough to sit on a grad school admissions committee as part of my training as a graduate student in social psychology. This view from the inside gave me some interesting information about what the GRE means to the most important people: the ones reading your application.
To start off, it’s important to understand exactly how admissions committees work. Admissions committees, especially for small programs, are not as organized or as consistent from year to year as you might think. This is because there is often a high degree of turnover in the grad school admissions committee staff from year to year. While with business schools there may be a fully-staffed admissions committee with only a handful of academics sitting in, in other programs the admissions committee consists entirely of professors and graduate students, many of whom are serving for their first time. What this means is that there is no secret formula for a winning application, since the committees change drastically from year to year.
However, there are certain aspects of your application that are sure to get you noticed by the grad school admissions committee. 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
