And now that it’s been a decade since you last simplified a quadratic or calculated an average speed, you’re feeling rusty. You’ve got a lot of work to do. Read more

Manhattan Prep GMAT Blog - Stop Careless GMAT Quant Errors 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.


Here’s a careless error that any of us might make:

x – 7 – 2x + 4 = 3x

-x – 3 = 3x

-3 = 2x

x = -1.5

Did you spot the error? If yes, give yourself a pat on the back and keep reading. If not, go back and review each step. This time, as you think through it, you can only use the terms added, subtracted, multiplied, and divided. On each line, identify which of those operations we used, and how we used it. Read more

A few weeks ago, I wrote about making the most of your ear as a native English speaker. Here’s the short version: you already know, intuitively, a lot of the grammar that GMAT Sentence Correction tests. But the GMAT takes simple grammar errors and buries them in long, boring sentences with lots of extraneous detail. To outsmart the GMAT, simplify and visualize the sentence in your head as you read it. This will help your ear to do what it does best.

Now let’s talk about when and why to use your ear. It’s okay to use your ear on GMAT Sentence Correction… under two conditions. Read more

What’s the deal with pronoun ambiguity on the GMAT?

Unfortunately, this question doesn’t have a short answer. Pronoun ambiguity is one area in which the rules of GMAT Sentence Correction are actually a little… ambiguous. (Sorry!) This article will describe what we know about the rules, and, more importantly, how you can use them to gain points on Sentence Correction. Read more

Check out these two sentences:

Why Do We Care about Yes/No Data Sufficiency Questions?

Manhattan Prep GMAT Blog - Why Do We Care about Yes/No Data Sufficiency Questions? by Chelsey Cooley

GMAT Data Sufficiency questions can seem a little mysterious. (If you’re just getting started, or if you need a refresher, here’s a great article on the basics of Data Sufficiency.) These problems are more like logic puzzles than math questions. That makes Data Sufficiency a good opportunity for those of us who want to score well on Quant, but don’t like doing math! However, you might have some questions about Data Sufficiency as you start to understand the problem type a little better. Here’s one of them: why do we categorize Data Sufficiency questions into “yes/no” and “value”? Read more

What Your Math Teacher Didn’t Tell You About PEMDAS

Manhattan Prep GMAT Blog - What Your Math Teacher Didn't Tell You About PEMDAS 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.


Here’s a phrase that might bring back some memories from middle school math class: Please Excuse My Dear Aunt Sally, or PEMDAS. (If you went to school outside of the U.S., you may have learned the acronym BEDMAS or BODMAS, instead.) You use this phrase to decide what order to do mathematical operations in: Parentheses first (from inside to outside), then Exponents, then Multiplication and Division (left to right), then Addition and Subtraction (also left to right).

PEMDAS isn’t terribly fancy stuff. It’s just a useful little tool that helps us communicate clearly—it’s what tells us, for instance, that “2x(3+4)” means something different from “2×3 + 4.” But if there’s one thing the GMAT loves, it’s making things look more complicated than they really are.

That’s a good question! Do you really need to solve all the GMAT problems in the Official Guide to the GMAT in order to score a 700? What about the other side of the issue: is it possible that there aren’t enough problems in the Official Guide? How many GMAT problems should you solve before taking the official GMAT?  

Before I share my answer, let’s get some facts on the table. Read more
