Find the Quickest Way to Solve for X on the GMAT

Find the Quickest Way to Solve for X on the GMAT

I like to compare the GMAT to everyday things that hopefully resonate with people. To that end, I often like to use the analogy of routes to work to compare the different methods one can use to get the answer to a question. Invariably, there are multiple ways to get to the right answer on a math question, just as there are multiple ways to get to work. Some are just more direct than others. If I work on the island of Manhattan and live on the island of Manhattan, I can detour through The Bronx to get to work, but I’ll probably waste a lot of time. However, that doesn’t mean that I won’t get there, so it is an acceptable route for work. Of course, most of us are usually looking for the quickest way to get to work (for some reason my boss gets testy when I show up 3 hours late).

How to Solve a Two-Part Analysis Question

How to Solve a Two-Part Analysis Question

Got the basics of the Integrated Reasoning formats, and ready to start with some questions? The Two-Part Analysis question is one of the most straight-forward IR question types. A short paragraph is followed by information in columns and rows. You’ll be asked to choose one answer from each column since the complete answer will have a “two-part” solution. Let’s look at a sample Two-Part Analysis question!

How to Determine the Author's Scope

In writing a weekly column for Veritas Prep, I try to cover topics and subjects that will help you avoid common pitfalls on the GMAT. The exam uses certain common traps and therefore it is better to review them routinely in order to be prepared to deal with such adversity on test day. Every type of question on the exam can have pitfalls and I’d like to cover the major ones in every question type. Today, we’ll take a look at Reading Comprehension.

How to Find the Sum of Integers on the GMAT

How to Find the Sum of Integers on the GMAT

In the quant section of the GMAT, there are a fair number of formulae to know in order to answer the ensemble of questions that may be asked of you. Most of them are covered in any basic test prep material, but a formula is always just a short hand version of a much longer manual process.

There is an anecdote about a primary school teacher who wanted to keep a misbehaved child busy for a period, so she asked him to sum up all the numbers from 1 to 100. To her dismay, the child answered the question in a matter of seconds, and the answer was correct. The child explained to his teacher that, instead of simply adding 1+2+3…, you could create a pairwise addition that would always yield the same number. If you added 1 to 100, you would get 101. If you added 2 to 99, you would still get 101. If you added 3 to 98, you’d still get 101, and so on. Thus the addition of 100 different numbers could be turned into a multiplication of two simple numbers: 101 x 50. The student in question was mathematical prodigy Carl Friedrich Gauss.

The Secret to Solving Word Problems

The Secret to Solving Word Problems

Word Problems tend to intimidate newcomers to the GMAT.  Don’t be scared!  The math on most word problems is actually easier and less troublesome than the math on a straightforward arithmetic or algebra problem.

The reason the math is easier on these problems is because the problem is made hard in other ways.  Word problems are considered hard because you have to convert a word problem into a math question.  This involves good reading skills and good critical reasoning skills.

Recognizing Illogical Modifiers on the GMAT

Recognizing Illogical Modifiers on the GMAT

Without descriptive words, phrases or clauses, sentences lack color.   A misstep of many is not paying close enough attention to the proper placement of modifiers.    The makers of the GMAT are aware of this shortsightedness of many test-takers.  As a result, they do test your ability to recognize illogical modifiers.

Parallel Reasoning Strategies: Part I

Parallel Reasoning Strategies: Part I

Parallel Reasoning questions on the Critical Reasoning section of the GMAT are a type of “method of reasoning” question-type. These questions require you to focus on the author’s logic. Parallel reasoning questions ask you to look for the answer choice that has the closest logical structure as the argument in the question stem. Ask yourself: which choice best matches the WAY the author moves from the evidence to his conclusion?

Conclusions are Key in Critical Reasoning

Conclusions are Key in Critical Reasoning

Critical reasoning questions on the GMAT tend to follow the same structure over and over again. This means that they can be answered the same way over and over again (like the movie Groundhog Day, but with words!). The first step is to determine which type of question you’re dealing with, which is why identifying the category is the first step towards successfully answering the question. The four major categories can be remembered with the mnemonic SWIM:

4 Tips to Bring Relief to Your GMAT Studies

4 Tips to Bring Relief to Your GMAT Studies

Any worthwhile MBA program is bound to cause some stress in the life of a student. Remember: if your MBA program didn’t challenge you at the highest level, it wouldn’t be worth it. That said, sometimes we make it hard on ourselves to de-stress in our GMAT study plan. Procrastination, lack of sleep, and taking on too much work are the most often-blamed culprits. If you find yourself “burning the candle at both ends,” try these techniques to bring a little relief!

A common complaint I hear from students is: “I’m not good at algebra”. Full disclosure, algebra isn’t my favorite topic either. Although algebra is a powerful tool for solving many questions on the GMAT, it is rarely the only means available to solve a given math problem.

The Importance of the Question Stem

The Importance of the Question Stem

There are so many types of Critical Reasoning questions that sometimes it’s confusing to tell your Method of Reasoning from your Argument Structure! Students are always instructed to read the question stems first and discern the specific category of CR question from them, but there’s another more important reason to hone in on the specific wording of the question stem: it gives away the answer!

The Secret to Causation/Correlation

The Secret to Causation/Correlation

You’ve probably read about or seen CR questions that confuse “causation” with “correlation,” but what does it mean in the real world? And why does it matter?

In statistics, let’s say we have data from two variables: x and y. They have a direct relationship. As one increases, the other increases. This could lead scientists to draw a conclusion that one variable causes the change in the other variable. But this isn’t necessary true! In fact, some third variable may be affecting both x and y! In order to prove causation and validate that one variable is indeed directly influencing the other and is the reason behind the detected correlation, further studies would need to be conducted, altering parameters, and recording outcomes.

7 Tips for Writing Your Argument Essay

7 Tips for Writing Your Argument Essay

The AWA section of the GMAT is made up of one short piece of writing called the “Argument” essay. It essentially asks you to evaluate an argument, usually a type of proposal. The main qualities that the readers look for are the organization of your ideas, the quality of the ideas themselves, the strength and relevance of the examples, and your grasp of standard written English. According to GMAC, the “Analysis of an Argument tests your ability to formulate an appropriate and constructive critique of a specific conclusion based on a specific line of thinking.” With that, let’s take a look at a few helpful tips:

Mental Calculations on the GMAT

Mental Calculations on the GMAT

One of the reasons calculators aren’t allowed on the GMAT is to ensure that people are really thinking about the numbers they are using to solve problems. Being at ease with mental math is a skill that has been slowly eroded since the advent and subsequent ubiquity of the calculator in the education process (sadly my frequent calls to bring back the abacus have gone unheeded). Too often, people mindlessly type in numbers, and don’t even notice if they hit the wrong number or a button gets pressed twice. Of course 5*6=45, the machine told me so! (Dependence on machines also eventually leads to Skynet) However, being good at mental math can be helped along if you already have a good idea which numbers you might expect to see on test day.

Breaking Down GMAT Modifier Questions

Breaking Down GMAT Modifier Questions

On the GMAT, an exam about reasoning and logic, there are few things more frustrating than long sentences punctuated by a host of modifiers, particularly prepositional phrases, participial phrases and appositive phrases, to say nothing of relative clauses. Sentence correction questions are about making sure there are no mistakes in a given sentence, and the more commas and modifiers a sentence has, the more difficult it is to ascertain whether or not it is structured correctly (hint: ~80% of the time, it’s not).

5 Properties of Zero

I spend a disproportionate amount of time thinking about the GMAT. It’s a very interesting exam that can be thought of from multiple angles. Most people see it as an obstacle to be surmounted in an effort to get into the business school of their choice. Some people see it as an unfortunate barrier to their future plans. Personally, I like to think of it as an opportunity to test your reasoning skills against an unseen test maker (who you can think of as the Wizard Oz from the namesake movie). Your goal is to stay one step ahead of the test and predict the traps that will be laid out for you as you answer questions.

Fans of the “Harry Potter” franchise know that the Sorting Hat magically determines which of the four school houses each new student is to be assigned at Hogwarts.

Similarly, on the “Table Analysis” questions in the Integrated Reasoning section on the GMAT, you are required to sift through data and draw conclusions. We may not have magic to help us, but sorting data isn’t as complicated as it sounds.

GMAT Gurus Speak Out: Understanding the Author's Argument

In Critical Reasoning questions, we know we have to understand the “author’s argument” – essentially his point of view that is expressed in the given paragraph, but it’s also important to narrow in on the “how” of the argument: the reasoning itself. The reasoning gives us the full “because.” For example, Nicki Minaj and Mariah Carey might both agree an American Idol contestant shouldn’t move on to the finals, but their reasoning could be very different. Maybe Mariah Carey doesn’t think the singer can hit the high notes, while Nicki Minaj may not think their outfits have enough pink feathers. Let’s look at a CR questions where the reasoning helps us find the correct answer:

The first step to tackling them is to make sure you did some solid note-taking on your first read of the passage. Unlike Detail questions, there are no line numbers to help you find the answer for tone/style questions. Only by paying attention to the author’s voice and style as you read will you be able to get these questions right.

On the GMAT, the information provided to you will be factual, but it won’t necessarily be helpful. Once you have made peace with this unfortunate reality, the goal soon becomes to transform factual information into useful information in order to solve the question. This type of analysis is prevalent in the quantitative section of the exam, but also shows up in the verbal section. Statements provided will often contain implicit information that you must convert into explicit information. In essence, you need to get a handle on the assumptions being made.
