How to Tackle Every Single GMAT Problem (Seriously!) – Part 5

by

Blog-Tackle-Pt5Welcome to part 5 of our series on how to answer every single GMAT problem you’ll ever see. :) If you haven’t already read the earlier installments, start with part 1 and work your way back to me.

Last time, I left you with a Critical Reasoning question from the free questions that come with the GMATPrep® software. Let’s talk about it! Read more

How to Tackle Every Single GMAT Problem (Seriously!) – Part 4

by

Blog-Tackle-Pt4Welcome to the fourth installment of our series: how to tackle every problem on the GMAT. If you’re joining in the middle, go back and learn about the set of principles that tie together everything we need to do on the GMAT. Then work your way back to this installment.

Here’s our framework again:

228 - Q Process 3

I finished off part 3 with the following GMATPrep® problem from the free exams. Let’s use the SC process to answer it now. Read more

The Importance of Getting to No on the GMAT — Part 1

by

Social-No-Pt1Recently, a colleague of mine shared this very interesting puzzle published by the New York Times. (Thanks, Ceilidh!)

Go ahead and try it. I’ll wait. After you’ve tried the puzzle, you can read the short article that goes with it.

What did you learn about how humans tend to think? More important, what did you learn about how you think?

That tendency to look for the no, or to try to disprove something, is a trait shared by scientists, devil’s advocates, and great standardized test takers. You can learn to make this your natural reaction, too!

GMAT Problem Solving Strategy: Test Cases

by

3-19-TestCasesIf you’re going to do a great job on the GMAT, then you’ve got to know how to Test Cases. This strategy will help you on countless quant problems.

This technique is especially useful for Data Sufficiency problems, but you can also use it on some Problem Solving problems, like the GMATPrep® problem below. Give yourself about 2 minutes. Go!

* “For which of the following functions f is f(x) = f(1 – x) for all x?

(A) f(x) = 1 – x
(B) f(x) = 1 – x2
(C) f(x) = x2 – (1 – x)2
(D) f(x) = x2(1 – x)2
(E)  f(x) = x / (1 – x)”

 

Testing Cases is mostly what it sounds like: you will test various possible scenarios in order to narrow down the answer choices until you get to the one right answer. What’s the common characteristic that signals you can use this technique on problem solving?

The most common language will be something like “Which of the following must be true?” (or “could be true”).

The above problem doesn’t have that language, but it does have a variation: you need to find the answer choice for which the given equation is true “for all x,” which is the equivalent of asking for which answer choice the given equation is always, or must be, true.

How to Switch from the GRE to the GMAT

by

GRE_TO_GMATLately, we’ve been talking about how to decide which test to take, as well as what to do if . What if you decide to switch from the GRE to the GMAT? That’s what we’ll tackle today! (We have also talked about what to do if you want to switch from the GMAT to the GRE.)

How do I study?

The overall way that you want to study doesn’t actually change that much; rather, you’ll just need to change what you are studying, as discussed later in this article.

First, you’ll need to determine whether the way that you’ve already been studying is actually the optimal way. If not, then you’ll need to make some changes, regardless of whether you stick with the GRE or switch to the GMAT.

The GRE and the GMAT are both executive reasoning tests; that is, the test makers want to know how you think and make decisions. You of course need to know content (certain facts, rules, formulas) in order to do well on either test, but that level of study is not enough; you also need to lift yourself to a second level of understanding that allows you to think your way through these sometimes bizarrely-worded problems as effectively and efficiently as possible.

Follow the two links I put in the last paragraph. Take some time to just think about the concepts presented there. Has this been your approach to studying so far? If so, great. Keep thinking and working in that way.

If not, however, recognize that you’re going to need to start studying with this new mindset, regardless of whether you take the GRE or the GMAT.

What are my strengths and weaknesses?

Any time you’re developing or revising a study plan, you’ll want to put together a solid analysis of your strengths and weaknesses.

If you have been studying for the GRE for a while, then you should have some practice CAT data. (If not, or if it has been more than 6 weeks since you last took a CAT, then you’ll need to take one to get the data. Make sure to take the test under official conditions, including the essays, length of breaks, and so on.)

Analyze your most recent two CATs (this link tells you how to analyze Manhattan Prep CATs). If you haven’t taken MPrep CATs, you can still read through that link to get an idea of how you want to analyze your data from another test. Your goal is to split all question types and content into one of three buckets:

Bucket 1: Strengths. I’ll still study and practice these but not as heavily as other areas.

Bucket 2: Low-hanging Fruit: These are my easiest opportunities for improvement. Careless mistakes. Things that I get wrong fast. Things that I get right but just a little too slowly.

Bucket 3: Weaknesses. These are areas that I’ll ignore until I’ve worked out my Bucket 2 issues. Things that I’m likely to get wrong even if I give myself unlimited time. Things that I get right but way too slowly. Things that use up way too much mental energy, even if I get them right.

Your primary focus until your next practice test will be working a lot to improve Bucket 2, while maintaining Bucket 1 skills and getting Bucket 3 questions wrong fast (yes, seriously!).

[Aside: there are certain things that will stay in Bucket 3 forever. I’m terrible at combinatorics and I’m pretty bad at 3D geometry. That’s been true since my very first practice GRE, more than 10 years ago! When I see these, I’ll give it a look in case the problem is very similar to one that I do remember how to do, but otherwise, I pick my favorite letter and move on.]

Okay, now that you know what your strengths and weaknesses are, you need to familiarize yourself with the differences between the GRE and the GMAT.

What new things do I have to learn?

The Essays and Integrated Reasoning

You won’t care as much about one difference, so let’s get it out of the way. At the beginning of the GRE, you write two essays. The GMAT also asks you to write an essay but in place of the second essay you’ll have to do the Integrated Reasoning section, a multiple-choice section that mixes quant and verbal skills.

This section is different enough from the others that you will have to study how to answer these questions and how to manage your time during the section. At the time of this publication (in March 2015), schools aren’t using IR scores much, so this section is less important, though this could change in the future.

Quant

Next, for the quant section of the test, you’re going to need to learn about one different question type contained on the GMAT: Data Sufficiency (DS).

The GMAT dives more deeply into number properties, story problems, and some algebra concepts, so you may need to get GMAT books for these topics versus continuing to use your GRE books.

The timing on the two tests is also quite different, so you’ll have to learn how to handle 37 questions in 75 minutes on the GMAT, or about 2 minutes per question on average.

Verbal

Most of your new efforts on verbal will be geared towards the grammar question type, Sentence Correction (SC). You’ll definitely need to get some materials that teach you the grammar and meaning issues that are tested on SC.

Again, if you are already using Manhattan Prep materials, you can use what you already have for Reading Comprehension (RC), but you will need to get new materials for Critical Reasoning (CR). The CR question types on the GRE are also tested on the GMAT, but the GMAT contains additional CR question types that don’t appear on the GRE.

Again, the timing will be different on the GMAT. You’ll need to answer 41 verbal questions in 75 minutes, spending about 1 minute 20 seconds on SC, 2 minutes on CR, and about 6 to 8 minutes total for RC passages and questions.

How do I make a study plan?

We’ve already talked about part of the process (analyzing your strengths and weaknesses). You may decide to take a class or work with a tutor, in which case your teacher will give you specific assignments . If not, you’ll need to develop your own study plan.

Takeaways for switching from GRE to GMAT

(1) Make sure that you’re going into your studies with the right overall mindset (executive reasoning!) and that you know how to lift yourself to the “second level” of study.

(2) Begin your studies by concentrating on the aspects that are new to you: the different question types and topics that are tested on the GMAT. Once you build those skills up to a competent level, you’ll review all aspects and question types.

How to Switch from the GMAT to the GRE

Want a Better GMAT Score? Go to Sleep!

by

2-12-Sleep-GMATThis is going to be a short post. It will also possibly have the biggest impact on your study of anything you do all day (or all month!).

When people ramp up to study for the GMAT, they typically find the time to study by cutting down on other activities—no more Thursday night happy hour with the gang or Sunday brunch with the family until the test is over.

There are two activities, though, that you should never cut—and, unfortunately, I talk to students every day who do cut these two activities. I hear this so much that I abandoned what I was going to cover today and wrote this instead. We’re not going to cover any problems or discuss specific test strategies in this article. We’re going to discuss something infinitely more important!

#1: You must get a full night’s sleep

Period. Never cut your sleep in order to study for this test. NEVER.

Your brain does not work as well when trying to function on less sleep than it needs. You know this already. Think back to those times that you pulled an all-nighter to study for a final or get a client presentation out the door. You may have felt as though you were flying high in the moment, adrenaline coursing through your veins. Afterwards, though, your brain felt fuzzy and slow. Worse, you don’t really have great memories of exactly what you did—maybe you did okay on the test that morning, but afterwards, it was as though you’d never studied the material at all.

There are two broad (and very negative) symptoms of this mental fatigue that you need to avoid when studying for the GMAT (and doing other mentally-taxing things in life). First, when you are mentally fatigued, you can’t function as well as normal in the moment. You’re going to make more careless mistakes and you’re just going to think more slowly and painfully than usual.

When Your High School Algebra is Wrong: How the GMAT Breaks Systems of Equations Rules

by

2-17-HighSchool-2If you have two equations, you can solve for two variables.

This rule is a cornerstone of algebra. It’s how we solve for values when we’re given a relationship between two unknowns:

If I can buy 2 kumquats and 3 rutabagas for $16, and 3 kumquats and 1 rutabaga for $9, how much does 1 kumquat cost?

We set up two equations:

2k + 4r = 16

3k + r = 9

Then we can use either substitution or elimination to solve. (Try it out yourself; answer* below).

On the GMAT, you’ll be using the “2 equations à 2 variables” rule to solve for a lot of word problems like the one above, especially in Problem Solving. Be careful, though! On the GMAT this rule doesn’t always apply, especially in Data Sufficiency. Here are some sneaky exceptions to the rule…

2 Equations aren’t always 2 equations

Tackling Max/Min Statistics on the GMAT (part 3)

by

2-12-MinMaxP3

Welcome to our third and final installment dedicated to those pesky maximize / minimize quant problems. If you haven’t yet reviewed the earlier installments, start with part 1 and work your way back up to this post.

I’d originally intended to do just a two-part series, but I found another GMATPrep® problem (from the free tests) covering this topic, so here you go:

“A set of 15 different integers has a median of 25 and a range of 25. What is the greatest possible integer that could be in this set?

“(A) 32

“(B) 37

“(C) 40

“(D) 43

“(E) 50”

Here’s the general process for answering quant questions—a process designed to make sure that you understand what’s going on and come up with the best plan before you dive in and solve:

gmat1

Fifteen integers…that’s a little annoying because I don’t literally want to draw 15 blanks for 15 numbers. How can I shortcut this while still making sure that I’m not missing anything or causing myself to make a careless mistake?

Hmm. I could just work backwards: start from the answers and see what works. In this case, I’d want to start with answer (E), 50, since the problem asks for the greatest possible integer.
