Some researchers estimate that there are as many as a million words in the English language. However, you won’t see words like mylohyoid, ekphrasis, or cotyledon on the GRE. In fact, even though English has a huge number of extremely rare words, the GRE almost never tests them. Instead, it focuses on a set of words we’ll call rare but reasonable. Read more

Manhattan Prep GRE Blog - Are GRE Verbal Questions Subjective? by Chelsey Cooley

A lot of people think that GRE Verbal questions can have more than one right answer. The GRE itself doesn’t do anything to dispel this myth, since Verbal questions often include wording like which of the following is best supported? or with which statement would the author most likely agree?. These questions make it sound as if you’re supposed to read five pretty good answers and pick the best one, even if the other ones are okay, too. However, this mindset will hurt you on test day.

A great flashcard is more than just a memory tool. It can also help you overcome that “not sure what to do next” feeling on test day. Here’s how to get the most out of every flashcard you create.

You don’t need to memorize that many facts to conquer GRE Quant. You should know the basic geometry facts and formulas, the definitions of math terms such as integer and quartile, and the first few primes and perfect squares. GRE Quant flashcards are a great way to drill yourself on those facts! But you can also use them for much more than just facts. Read more

Nine identical machines, each working at the same constant rate, can stitch 27 jerseys in 4 minutes. How many minutes would it take 4 such machines to stitch 60 jerseys?

First, take a deep breath. In this article, you’ll learn a methodical approach that will work on GRE rates problems every single time. On test day, it’ll be tempting to throw away your new habits and go back to old ones. Try to do the opposite. You’ve done all of this studying for a reason!

On problems like this, don’t try anything fancy. A lot of GRE test-takers will try to logically reason their way through this problem, saying something like “well, if 9 machines stitch 27 jerseys in 4 minutes, then 3 machines stitch 9 jerseys in 12 minutes…” That approach is valid but dangerous. Whenever you choose not to write something down, you’re taking away your ability to check your work for mistakes. (By the way, where’s the mistake in the logic described above?)

To start the problem, make a table. Your scratch paper should look like this: Read more

“When I See This, I Will Do This”: A GRE Study Tool

“I know all of the rules, but I’m nowhere close to my goal score.”

“When I study, I understand everything right away. But when I took the actual GRE, I couldn’t make it happen.”

“I never know what to do when I see a Quant problem for the first time. If somebody tells me how to set the problem up, I can do it perfectly, but I can’t get started on my own.”

“I get overwhelmed by Verbal questions. I’ll think that my answer makes sense, but then I’ll review the problem and realize that there were a dozen different things I didn’t notice.” Read more
