I don’t know about you, but I’m pretty lazy when it comes to doing math on paper. Blame constant access to Excel and the calculator on my phone…but I’m completely over doing math on paper.

If you give me a problem that’s going to require half a page of calculations…well, I’m not going to want to do that problem. But on the GMAT Quant section, I don’t get a calculator, so how can I still get a 99th percentile score while staying true to my lazy-math desires?

Let’s do some Fast Math! Read more

Error Log: The #1 Way to Raise Your GMAT Score!!

Manhattan Prep GMAT Blog - The #1 Way to Raise Your GMAT Score: The Error Log!! by Elaine Loh

Did you know that you can attend the first session of any of our online or in-person GMAT courses absolutely free? We’re not kidding! Check out our upcoming courses here.


This is not hyperbole. I truly believe that the number one way to raise your score is to have a thorough error log. I have had a number of students who come to me after having gone through most of the Official Guide but who are still struggling to get the scores they want. When I ask, “What do you have to show for doing ALL of these problems?” the answer is often something along the lines of “I’m not sure.” That drives me bonkers! I want you to work smart, not hard.

Manhattan Prep GMAT Blog - Know the GMAT Code: Interest Rate GMAT Problems by Stacey Koprince

Did you know that you can attend the first session of any of our online or in-person GMAT courses absolutely free? We’re not kidding! Check out our upcoming courses here.


I’m excited about the problem I have to share with you today in the latest installment of our Know the Code series. Interest rate GMAT problems can be extremely annoying—you might find yourself spending 4 minutes and still having to guess in the end. So your first decision is whether you even want to tackle these kinds of problems in the first place.

But there are some things you can learn that could make answering interest rate GMAT problems a lot less irritating. Try out this Integrated Reasoning (IR) Two-Part problem from the GMATPrep® free practice exams. (Note: This one is an IR question, but I could absolutely see them testing the same principle on a Quant problem.) Read more

In the previous articles in this series, we developed a critical skill for GMAT probability and combinatorics problems: listing out cases. Let’s start by taking another look at the practice problem from the end of the last article. Read more

GMAT Grammar: Using Nor Without Neither

Manhattan Prep GMAT Blog - GMAT Grammar: Using Nor Without Neither by Emily Madan

Did you know that you can attend the first session of any of our online or in-person GMAT courses absolutely free? We’re not kidding! Check out our upcoming courses here.


This is the first in what I hope will be many student-question inspired posts. Allyson from Philadelphia was wondering whether “nor” had to be paired with “neither” or whether it could be used on its own. The answer was far more complex than expected, so here it is. If you have an idea for a GMAT grammar blog post, or just have a question that you want answered, email me at emadan@manhattanprep.com.

To begin, you’ll need to understand the essentials of parallelism. You can get in-depth coverage of parallelism in our Sentence Correction Strategy Guide, but here are the basics. Two (or more) things in a list have to be both structural and logically parallel. Let’s start with the positive form: either/or. Read more

How to Handle 3-Group Overlapping Sets on the GMAT

Manhattan Prep GMAT Blog - How to Handle 3-Group Overlapping Sets on the GMAT by Reed Arnold

Did you know that you can attend the first session of any of our online or in-person GMAT courses absolutely free? We’re not kidding! Check out our upcoming courses here.


Most overlapping sets on the GMAT have two distinct groups. Students take French and/or Spanish (or neither), pianists play either classical and/or jazz (or neither), people like either QDoba and/or Baja Fresh (definitely neither. Chipotle, please)—and for these situations, the familiar, double-set matrix approach works best. Read more

If you’re in college, business school might sound like a faraway, almost ominous concept. Do you have a dream business school that you want to attend one day? Do you know what it takes to get into a top b-school? Have you heard about the GMAT, or Graduate Management Admissions Test?

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

Manhattan Prep GMAT Blog - Help! I Can't Handle GMAT Probability and Combinatorics (Part 2) by Chelsey Cooley

Did you know that you can attend the first session of any of our online or in-person GMAT courses absolutely free? We’re not kidding! Check out our upcoming courses here.


In the previous article in this series, we introduced two big ideas about GMAT probability and combinatorics:

  1. Most people find them counterintuitive.
  2. The best way to get past that is to list the possibilities.

In this article, we’ll focus more on #2. How do you list out the possibilities in a GMAT probability or combinatorics problem? Let’s try it on a simple probability problem. Read more

How to Hack GMAT Reading Comprehension: Think Like a Lawyer!

Manhattan Prep GMAT Blog - How to Hack GMAT Reading Comprehension: Think Like a Lawyer! by Ceilidh Erickson

After working with thousands of students, I’ll admit: Reading Comprehension is my least favorite subject to teach. Why? Because unlike Quant or grammar, 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 GMAT 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
