How to Manage Unmanageable Numbers on the GMAT

How to Manage Unmanageable Numbers on the GMAT

When going through the quantitative section of the GMAT, you will often be confronted by numbers that are, shall we say, unwieldy (some people refer to them as “insane”). It is common on the exam to see numbers like 11!, 15^8, or even 230,050,672. Regardless of the form of the number, the common mistake that many novice test takers make is the same: They try to actually solve the number.

How to Go from a 48 to 51 in GMAT Quant - Part V

First, let us give you the link to the last post of this series: Post IV. It contains links to previous parts too.

Today, we bring another tip for you to help get that dream score of 51 – if you must write down the data given, write down all of it! Let us explain.

GMAT Tip of the Week: Why Are You Here?

GMAT Tip of the Week: Why Are You Here?

This week’s video post brings you a tip for taking a closer look at the data in Data Sufficiency. Is what you know about Data Sufficiency statements really sufficient? There are certain points of information that are necessary to know for Data Sufficiency, but knowing those doesn’t mean you have sufficient information to correctly solve the problem.

1 Simple Way to Solve Puzzling GMAT Questions

If you’ve ever built a puzzle, you probably know that you can’t expect to start at a certain point and build the entire puzzle without moving around. You may find two or three pieces that fit together nicely, but then you find three pieces that fit together nicely somewhere else, and then work to connect these disparate sections.

The Holistic Approach to Mods on the GMAT - Solutions

The Holistic Approach to Mods on the GMAT - Solutions

First, we would like to refer you back to a post we put up quite a while ago: The Holistic Approach to Mods

In this post, we discussed how to use graphing techniques to easily solve very high level questions on nested absolute values. We don’t think you will see such high level questions on actual GMAT. The aim of putting up the post was to illustrate the use of graphing technique and how it can be used to solve simple as well as complicated questions with equal ease. It was aimed at encouraging you to equip yourself with more visual approaches.

Think Inside the Box on Tricky GMAT Questions

Think Inside the Box on Tricky GMAT Questions

When dealing with questions that ask us to compartmentalize information, there are two major sorting methods that we can use on the GMAT. The first, and perhaps more familiar concept, is the Venn diagram. This categorization is very useful for situations where information overlaps, as it allows a visual representation of multiple categories at once. However, if the information provided has no possible overlap, such as indicating whether something is made of gold or silver, or if they’re male or female (Bruce Jenner notwithstanding), the preferred method of organization is the matrix box.

A 750+ Level Question on SD

A 750+ Level Question on SD

A couple of weeks back, we looked at a 750+ level question on mean, median and range concepts of Statistics. This week, we have a 750+ level question on standard deviation concept of Statistics. We do hope you enjoy checking it out.

Before you begin, you might want to review the post that discusses standard deviation: Dealing With Standard Deviation

Understanding 1337 GMAT Logic

Understanding 1337 GMAT Logic

One of the most difficult tasks on the GMAT is to properly interpret what the question is really asking. The GMAT is loaded with dense terminology, accurate but irrelevant prose and confusing technical jargon (and that’s just the instruction page!) The verbiage is dense on purpose, with the deciphering of the information part of the skills being tested. And since this task only gets more challenging as you get more tired throughout the exam, it’s important to recognize the vocabulary used on the GMAT. To borrow from geek culture, you need to understand the GMAT 1337 speak.

How to Interpret Unfamiliar Symbols on GMAT Quant Questions

How to Interpret Unfamiliar Symbols on GMAT Quant Questions

Succeeding on the GMAT requires a great many things. Firstly, you must be able to decipher and solve complex logic puzzles in mere minutes. Secondly, you must be able to maintain focus for many consecutive hours. (And thirdly, you must pay to take the exam). The exam can be particularly tricky because the questions asked are rarely straight forward. Indeed, all of these elements are often linked (except potentially the payment) on questions that ask you to decode functions specific to the question at hand.

First Do What You Know on GMAT Questions

First Do What You Know on GMAT Questions

We have read a lot about one way of handling complex questions – simplify them to a question you know how to solve. Here is another way – first do what you do know, and then figure out the rest!

We know that basic concepts are twisted to make advanced questions. Our aim is to break down the question into two parts – ‘the basic concept’ and ‘the complexity’. You can either deal with the complexity first and then glide through the basic concept or you can glide through the basic concept first and then face the complexity. The method you use will depend on the question. If the question seems too complex at the outset, it means you will have to deal with the complexity first. If the question seems familiar but has some extra not-so-familiar elements, it means you should get the familiar out of the way first. Let’s take a question today to see how to do that.

GMAT Tip of the Week: Derek Jeter and the Data Sufficiency Walkoff

GMAT Tip of the Week: Derek Jeter and the Data Sufficiency Walkoff

It all looked so obvious: a storybook ending preordained from the beginning, some early success and a bit of good fortune leading to a glorious success story. But wait! Then fate intervened, and the easiest part of all had something different to say. And only then was true glory to be had, a glory much greater than that inevitable win ripped away just moments ago.

How to Expect the Unexpected on the GMAT

How to Expect the Unexpected on the GMAT

Most of us know that GMAT is a shrew, (euphemism for a more choice adjective that comes to mind!) and is very hard to tame. It is well established that it is able to give a pretty accurate estimate of aptitude with just a few questions, and that the only way to “deceive” it is by actually improving your aptitude! It has numerous tricks up its sleeves to uncloak a rather basic player.

GMAT Tip of the Week: At (the very) Least You Should Know This About Probability

GMAT Tip of the Week: At (the very) Least You Should Know This About Probability

Ah, autumn. The busiest GMAT season of the year as application deadlines and back-to-school nostalgia fill the air, and that season always coincides with Major League Baseball’s pennant races and playoffs. And whether you’re a baseball fan or not, as an aspiring MBA you’ll find a fair amount of overlap between the two, as both the GMAT (and business) and baseball prominently feature the art of probability.

How to Correctly Solve Vague GMAT Questions

How to Correctly Solve Vague GMAT Questions

Questions on the GMAT can be described in many different ways. I’ve heard them described as everything from juvenile to vexing, simple to impossible. One term that appears very infrequently as a characteristic of the questions on the GMAT is the word “clear”.  Indeed, some questions are so convoluted that they appear to be written in Latin (or Aramaic if you happen to already speak Latin). This is not a coincidence or an accident; many GMAT questions are specifically designed to be vague.

95% of Students Find This GMAT Quant Question Difficult

Today we continue to look at ways to achieve that much desired score of 51 in Quant. Obviously, we don’t need Sheldon Cooper’s smarts to realize that for that revered high score, we must do well on the high level questions but the actual question is – how to do well on the high level questions?

How to Free Yourself from Calculator Math

How to Free Yourself from Calculator Math

There are few things more alluring than shortcuts. Oftentimes we’re aware of how much work, effort or time is required to accomplish a task, but we naturally gravitate towards something that can accomplish that task faster. From buying readymade rice to taking elevators to go up two floors, we’re drawn to things that make our lives even a modicum simpler (including dictionaries). This is why so many people are disappointed when they first learn that the calculator is not allowed on the GMAT.

A 700+ GMAT Quant Question on Races

This week we will look at the question on races that we gave you last week.

Question 3: A and B run a race of 2000 m. First, A gives B a head start of 200 m and beats him by 30 seconds. Next, A gives B a head start of 3 mins and is beaten by 1000 m. Find the time in minutes in which A and B can run the race separately?

2 Simple GMAT Quant Questions That Will Help You Score Higher

Let’s discuss races today. It is a very simple concept but questions on it tend to be tricky. But if you understand how to handle them, most questions can be done easily.

A few points to remember in races:

1. Make a diagram. Draw a straight line to show the track and assume all racers are at start at 12:00. Then according to headstart, place the participants.

Should You Double Check Your Answer Choices on the GMAT?

Should You Double Check Your Answer Choices on the GMAT?

A common mantra heard when studying for the GMAT is that you have to be fast when answering questions. This is absolutely true, as the exam is testing not only your reasoning skills but also your time management skills. This does not, however, necessarily mean that you must solve every question quickly. Indeed, there may be times where you feel fairly confident in the answer choice you’ve selected, but you don’t feel 100% certain (maybe a strong 60%). In these situations, it’s perfectly acceptable to double check your answer manually.

As pointed out by a reader, we need to complete the discussion on a question discussed in our previous ‘Advanced Number Properties’ posts so let’s do that today. Note that the discussion that follows doesn’t fall in the purview of GMAT and you needn’t know it. You will be able to solve any question without taking this post into account but that has never stopped us from letting loose our curiosity so here goes…

How to Do Math on the GMAT Without Actually Doing Math

How to Do Math on the GMAT Without Actually Doing Math

On the GMAT quantitative section, the exam is testing your logic and analytical skills using mathematics as a medium. The topics used include geometry, algebra and arithmetic, all concepts that have been covered in high school curriculums around the world. However, the emphasis is really on the logic more than the math. In short, the question is simply asking you to solve a given problem by any means at your disposal. As such, many questions can be solved without doing any math whatsoever.

How to Go From a 48 to 51 in GMAT Quant - Part III

Let’s get back to strategies that will help us reach the coveted 51 in Quant. First, take a look at Part I and Part II of this blog series. Since the Quant section is not a Math test, you need conceptual understanding and then some ingenuity for the hard questions (since they look unique). Today we look at a Quant problem which is very easy if the method “strikes”. Else, it can be a little daunting. What we will do is look at a “brute force” method for times when the textbook method is not easily identifiable.

Find Out How Algebra Could Be Your Key to Success on the GMAT Quant Section

Find Out How Algebra Could Be Your Key to Success on the GMAT Quant Section

If you want to bring your “A Game” on the Quant section you need to be very comfortable with Algebra.

There is one mathematical discipline that dominates the Quant section of the GMAT: Algebra. The majority of the math questions that you will see on test day involve algebra.

Many questions involve pure algebra, such as expressions and equations involving variables, roots, and exponents. Another large group of questions is word problems, most of which are best addressed using algebraic equations. Geometry is another significant subject on the GMAT; and geometry is simply a delivery mechanism for algebra. Even things like ratios can often best be addressed by using equations with “x” as the multiplier.

Distract Yourself During Your GMAT Studies with This Question

Distract Yourself During Your GMAT Studies with This Question

In life, it’s important to have a hobby or pastime that you find interesting. Sometimes, when the daily grind of work, school, family, social responsibilities, (updating Facebook) and preparing for the GMAT just seems like too much to handle, it’s good to take a step back. Diving into a hobby helps take your mind off things by pausing everything else and concentrating on something personal and somewhat intimate to you. One of my favorite diversions is watching movies and immersing myself in the fictional world created on screen. Surprisingly, this same distraction can be applicable to GMAT studying as well.

This question is very hard to answer since we don’t have a step by step plan – do theory from here – do questions from there – take a test from here – read posts from there etc. Today and in the next few weeks, we will discuss how to go from 48 to 51 in Quant.

GMAT Tip of the Week: LeBron James Says Don't Be Cavalier About Your Initial Data Sufficiency Decision

GMAT Tip of the Week: LeBron James Says Don't Be Cavalier About Your Initial Data Sufficiency Decision

It’s all anyone can talk about today – LeBron James has decided to reverse “The Decision” and return home to play for Cleveland. In doing so he forced many people to change their minds.

Let’s take a look at some of those people:

-LeBron himself, who once decided to leave and now comes home as the prodigal son
-Cavaliers owner Dan Gilbert, who once wrote a scathing letter about James the week he left the Cavs for South Beach
-Cavaliers fans, who once burned LeBron’s jersey and rallied against him
-Dwayne Wade, who just last week opted out of a $40 million contract to restructure his deal to create space to attract more players to his and LeBron’s Heat team

Find the Correct Answer for Diagonals of a Polygon in This GMAT Question

In today’s post, we will give you a question with two solutions and two different answers. You have to find out the correct answer and explain why the other is wrong. But before we do that, let’s give you some background.

Given an n sided polygon, how many diagonals will it have?

An n sided polygon has n vertices. If you join every distinct pair of vertices you will get nC2 lines. These nC2 lines account for the n sides of the polygon as well as for the diagonals.

Determining How Much Time to Spend on GMAT Quant Questions

Determining How Much Time to Spend on GMAT Quant Questions

On the GMAT, you will be asked to answer multiple questions in a relatively short period of time. One of the main difficulties test takers have with the GMAT is that they run out of time before finishing all the questions. For the quant section, there are 37 questions to solve in 75 minutes, which gives an average of just over two minutes per question. Since you don’t want to finish at the 74:59 mark (unless you’re MacGyver), you can figure two minutes per question as a good target. The good news is that most questions can easily be solved within a two minute timeframe. Unfortunately, many test takers spend three or four minutes on questions because they do not understand what they are trying to solve.

The Reason Behind Absolute Value Questions on the GMAT

The Reason Behind Absolute Value Questions on the GMAT

Even after working extensively on absolute value questions, sometimes students come up with “why?” i.e. why do we have to take positive and negative values? Why do we have to consider ranges etc. They know the process but they do not understand the reason they need to follow the process. So here today, in this post, we will try to explain the reason.

Easy (A)/(B) Trap in Data Sufficiency Questions on the GMAT

Easy (A)/(B) Trap in Data Sufficiency Questions on the GMAT

We know that ‘Easy C’ is a common trap of DS questions – have you wondered whether there could be trap called ‘Easy A/B’ such that the answer would actually be (C)? Such questions also exist! The point is that whenever you feel that the question was way too simple, you might want to take a step back and review. GMAT will try every trick in the trade to delineate you. Let us show you a question which looks like an easy (A) but isn’t:

Avoiding Traps in GMAT Quant Questions

Avoiding Traps in GMAT Quant Questions

A common mantra at Veritas Prep is that the GMAT is a test of how you think, not of what you know. This shouldn’t be interpreted to mean that you can go into the exam without knowing anything and expect to get a good score. Rather, it means that how you apply concepts is crucial in this exam. You need to have a strong base, like the foundation of a house, but the difficulty is in using the information you have to solve the problem in front of you.

How Would You Solve This Data Sufficiency GMAT Question?

How Would You Solve This Data Sufficiency GMAT Question?

The question format least familiar to most prospective GMAT students is unquestionably Data Sufficiency. As a test exclusive (it has a no trade clause) question type, it is unlikely that you have come across such a question without having at least glanced at a GMAT prep book. However the format is completely logical. The question is asking when do you have sufficient data to answer a question, be it “always yes”, “always no” or “specific value x”. The enemy is uncertainty; any definitive answer will suffice to answer the question and move on to the next hurdle.

Rounding Up Some Official GMAT Questions!

Last week we looked at some rounding rules. Today, let’s go over some official questions on rounding. They are quite simple and if we just keep the “Slip to the side and look for a 5” rule in mind, they can be easily solved.

How to Solve Simple Math Equations on the GMAT

How to Solve Simple Math Equations on the GMAT

Many students who take the GMAT come from backgrounds that stressed mathematics. A significant percentage of GMAT test takers come from engineering backgrounds or other fields that require strong analytical skills. However, these students often find that the GMAT quantitative section is challenging for them. This is because the GMAT tests math in a way that is unfamiliar to these students, taking them out of their comfort zones and requiring them to solve questions in new and unfamiliar ways (most glaringly, without a calculator).

You just slip to the side, and you look for a five.

Well if the number that you see is a five or more, 

You gotta round up now, that’s for sure.
