# GRE Probability Practice: Strategy and Shortcuts

April 18, 2014 by

Although probability isn’t tested with high frequency on the GRE, it’s a concept that GRE students ask about (and stress out about) often. You’re best served devoting the majority of your time to topics that show up most commonly on the exam, such as arithmetic, algebra, and geometry. However, if you are hitting the high percentiles in math and aiming for a really strong GRE math score, it’s worth having a good understanding of basic probability concepts that you can use on the exam.

#### Probability Shortcuts

The practice problem we posted on Facebook  is an example of the type of question you might see on the GRE if you’re hitting around the 80th percentile and above. In a previous series on probability, we discussed how to approach these “at least” problems. In short, solve for the probability of the desired outcome NOT happening, and subtract … Read full post

# Make GRE Math Calculations Simple

April 17, 2014 by

ETS, the maker of the GRE, posted a guide to the on-screen calculator on their site. The guide itself is very good, but I’d like to give special attention to a few of its points. Correctly using — or, more importantly, not using — the GRE on-screen calculator on Test Day has a big impact on your performance.

My favorite bit from the test maker’s guide was this tantalizing suggestion:

Avoid using [the on-screen calculator] for simple computations that are quicker to do mentally, such as 10 – 490, (4)(70), 4,300/10, sqrt(25), and 30^2.

I call this advice “tantalizing” because it’s absolutely correct — but the author doesn’t specify why the example computations are considered “simple.” Some students may not know why, for example, (4)(70) should be computed mentally. Let me show you why all of the above computations are, indeed, simple.

# Looking for Patterns in GRE Arguments

April 15, 2014 by

While students often find it easy to spot patterns in the Quantitative section of the GRE, doing so in the Verbal section can seem like a more arduous task. This can be especially true in Critical Reasoning questions—those that ask you to evaluate an argument and then point out its flaw or assumption, or strengthen or weaken the author’s conclusion. To many students, each of the arguments they see on the test seems like a unique riddle to solve. But approaching every argument as its own, separate, special argument is a frustrating and inefficient way to move through this section of the test.

As you work through Critical Reasoning questions in your practice and homework, pay attention to the common argument patterns that the GRE tests over and over and over again. There are only a small number of types of arguments you’ll see on the test, and once you … Read full post

# Find Clues, Earn Points in GRE Verbal

April 14, 2014 by

The #1 mistake you can make on short GRE verbal problems is looking at the choices too soon. When you solve a short verbal problem, whether it’s a text completion or a sentence equivalence, you should predict what kind of word should go in the blank before you look at the choices.

Think of it this way: the test makers aren’t your friend. They’re not trying to help you out. This means that they’re not just going to write random wrong answer choices; they’re going to write wrong answers that will influence your thinking. Don’t fall for that nonsense.

#### Using Clues to Make Predictions

Here’s a relatively straightforward problem that turns ugly if you look at the choices too soon:

The Leonidas Achievement Award, though ostensibly prestigious, is held in low repute by some scholars who claim that favoritism runs rampant and that the judges are ______.

# GRE Sentence Equivalence Basics and Practice Question

April 11, 2014 by

Yesterday, we posted a practice GRE Sentence Equivalence Question on our Facebook page. Check it out.

Since there are six choices, you know what kind of question this is: Sentence Equivalence. Your task is to pick two words that both fit the sentence and produce an equivalent effect.

Let’s review GRE Sentence Equivalence basics first before diving into the explanation.

#### GRE Sentence Equivalence Basics

• Types: only one type with six answer choices
• Frequency: you will encounter approximately 4 SE questions in each GRE Verbal section
• Pacing: You should aim, by test day, to take about 1 minute per question for each SE question
• Directions: You must select the two answer choices that, when used to complete the sentence, fit the meaning of the sentence as a whole and produce completed sentences that are alike in meaning.
• Details: There is no partial credit – you must select both (and only) the

# The First GRE Prep Course eBook for Kindle

April 10, 2014 by

Great news for Kaplan students: we’ve collaborated with Amazon to bring the first GRE prep course ebook directly to students enrolled in Kaplan courses using the Kindle reading apps and Kindle Fire tablets. This makes our GRE course the first Kindle-compatible Kaplan course available for aspiring graduate school students. Kaplan GRE students will have the ability to study across multiple devices—Kindle Fire and Android tablets, iPads, PCs and Macs—and take advantage of features such as note taking, highlighting, tracking progress, word look up, searching and syncing.

“Until recently, the adoption of tablets and eBooks for studying has lagged the adoption of eBooks for leisure reading, because studying involves engagement with the book through highlighting, note-taking and other tactile actions,” said Lee Weiss, Executive Director of Emerging Products, Kaplan Test Prep. “But as these functions became more user-friendly in eBook form and device ownership continues to grow, we’re now seeing a … Read full post

Studying for the GRE is critical to Test Day success. You must learn the structure of test, familiarize yourself with GRE strategy, master methods and strategies for every question type, and review content such as math concepts and vocabulary. With all the work that you’re going to be putting in to preparing for the GRE, you’ll be pleased to know that this prep work can help you accomplish more than simply doing well on the GRE.

Many of the skills that will help you succeed on Test Day can also help you succeed in your graduate school admission process. I recommend that you get your GRE studying in first, take the test and get the score that you need for the programs you are applying to, and then dedicate the time your graduate school applications.

# An Easier Approach to GRE Combination and Permutation Problems

April 7, 2014 by

“Paula is selecting some books from a collection of seven books. How many different groups of four books can Paula select?”

Does seeing a question like this fill you with dread and anxiety? If you’re like most GRE students, there’s a good chance that it does. Questions that ask you to determine the number of groups that can be selected from a larger group, or that ask you to determine the number of ways a smaller group of entities can be arranged, are called GRE Combination and Permutation problems. If you’ve been studying for the GRE, you know these problems. For many students, these questions seem extremely difficult, if not impossible.

Well, I have good news: these questions aren’t actually all that difficult. What’s difficult, for many students, is memorizing large, convoluted formulas like this:

$_{n}\textrm{c}{_{r}}&space;=&space;\frac{n!}{r!&space;(n-r)!}$

Now, formulas are certainly valuable, and they serve an important service: by memorizing the formula, Read full post

# GRE Special Triangles Will 30(Rock)-60-90 You

April 4, 2014 by

My GRE students are quite aware of my love of the show 30 Rock. I always find a way to work it into our before-class chat and even into our lessons.

That’s because 30 Rock, if you haven’t seen it, is one of the most brilliantly written shows on television. Tina Fey and her adroit team of writers weave together countless and disparate plotlines into one homogenous, hilarious conclusion. The reason I bring this up is that the very same thing happens with the quantitative content on the GRE. It’s slightly less hilarious, but it really does all come together.

Case in point: special triangles. Knowing these is a GRE lifesaver, as long as you know how to use them. The problem is, they require some prerequisite math knowledge to be used to their best advantage.

Any Kaplan student with a laminated strategy sheet can tell you that a … Read full post

# How Would They Score on the GRE? The Walking Dead Edition

April 3, 2014 by

With the season finale of The Walking Dead behind us (I’m still recovering!), everyone I know continues to buzz over the thrill ride that was season 4. Don’t worry, no spoilers here, but it got me wondering how these characters, who deal with incredible life-or-death challenges, would fare if faced with taking the GRE. So, here are my guesses based on the characters as I’ve seen portrayed in the series and what I know about their lives previous to Walker-palooza (aka the zombie apocalypse.)

#### Rick Grimes

A small-town sheriff’s deputy who is wounded in the line of duty and wakes to a zombie apocalypse. An everyman, Rick struggles to cling to his moral code in the face of increasingly dire circumstances. Rick is sincere and hardworking, but his fatal flaw is that he second guesses himself and changes his mind too much – … Read full post
