# GMAT & The Real World: Critical Reasoning Flaws

November 22, 2013 by

A Study Questioning the GMAT Ironically Proves to be a Great Resource to Practice GMAT Critical Reasoning Flaw Questions…

Maybe you heard about a recent story in the Washington Post entitled: Are business schools graduating the wrong leaders? If so, the GMAT may be to blame.

The reason why I love this piece is because the study (at least as it is presented in the article) is jam-packed with critical reasoning flaws you can use to sharpen your GMAT Critical Reasoning skills.

That’s why I’ve decided to make this a multi-part special.

In our first installment, one of the reasoning flaws that the GMAT tests is starkly evident. Let’s see if you can identify it:

“A study in the Journal of Business Ethics makes the surprising finding that high GMAT scores may be correlated to some of the negative traits of American business: lack of ethical orientation…

# GMAT Question of the Week: Data Sufficiency and Averages – The Explanation

November 6, 2013 by

If you haven’t already, visit our Data Sufficiency practice problem and give it a try on your own before reading the explanation.

To get this question correct, you must combine your knowledge of fundamental math concepts with use of the Kaplan Method and strategies for approaching Data Sufficiency. Here’s a breakdown:

The average formula is Average = Sum of the terms / Number of terms.

The average of m and n is (m + n) / 2  . The question stem says “Is  (m + n) / 2  < 50 ?”

Remember, with a Yes/No Data Sufficiency question, you are looking at the statements and trying to determine whether they provide a consistent YES or NO answer to this question. A consistent answer of yes OR no is sufficient. An inconsistent answer (yes and no) is insufficient.

Statement (1): Sufficient. This statement says that (3m + 3n) / 2 … Read full post

# GMAT Answer of the Week: More Data is Sufficient

October 17, 2013 by

For those of you who were busy working on the answer to last week’s question of the week either via the blog post or via the Facebook page.  The answer is below.  Stay tuned as well. More questions coming this week.

Question:

Is x > y?

(1) 9x = 4y

(2) x>-y

Step 1: Analyze the Question Stem

This is a Yes/No question. The stem does not give us much information, so let’s go directly to the statements, looking for information about the relationship between x and y.

Step 2: Evaluate the Statements Using 12TEN

Let’s rewrite Statement (1) as 9x/4= y. Now we can use Picking Numbers. If x = 4, then y = 9, so x is not greater than y in this case. But x could also be negative. If x = -4, then y = -9, and now x is greater than … Read full post

# GMAT Question of the Week: Data Sufficiency

# GMAT Problem Dissection: Probability Part 2

July 25, 2013 by

Alright, you’ve been studying the GMAT basics. You understand what is really being tested along with the problem types, methods, and strategies. You’ve even memorized all the basic formulas and taken a dive into some of the more challenging content areas. So what’s next? That’s simple, practice…over and over and over again. If you do this, you are likely to start hitting tough probability questions at some point. Along with combinations and permutations, this is a content area that the GMAT can use to up the degree of difficulty quite a bit. So let’s take a look at a tough probability question and break it down:

A fair coin is tossed five times. What is the probability that it lands heads up at least twice?

(A) 1/16

(B) 5/16

(C) 2/5

(D) 13/16

(E) 27/32

The key to solving this is the phrase ‘at least twice.’ This means that … Read full post

# GMAT Tech

September 8, 2012 by

The GMAT is in some ways a technological marvel. Thanks to the wonders of the internet, thousands of locations across the globe are instantly reporting scores on the same test. The computer-adaptive test adapts to your skill level, adjusting difficulty on a question by question basis. Every center is equipped with a state-of-the-art scanner that records examinees’ handprints as a security measure.

Unsurprisingly, technology can also help you prepare for this test. Every GMAT student knows that paper-based quizzes can’t produce a test-like experience. Full-length practice Computer Adaptive Tests, like those offered by Kaplan and from www.mba.com, are key to success. But you can take the online prep a step further; most GMAT prep books, like Kaplan’s or the Official Guide, are also available as PDFs. Learning your lessons from a tablet or computer screen get your eyes used to reading on a monitor, and forces you to … Read full post

# Master Reading Comprehension Question Types: Part II

September 6, 2012 by

In a blog last last week, I talked about the importance of identifying the common question types in the reading comprehension portions of the GMAT and delved into the specifics for detail and global questions. Today, let’s continue that deeper look at the specifics for the common reading comprehension questions with a look at inference and function (logic) questions.  Specifically let’s look at how to spot them, how to predict using the pattern behind the question, and how to spot the most common wrong answer types. Both of these questions generally constitute the harder or more commonly missed set of questions in the reading comprehension.

One of the most commonly missed reading comprehension questions is the inference question because of how it is treated on tests versus our common everyday use of inference. First of all, to spot them you are looking either for something that references “is … Read full post

# Tough GMAT Problems: When Should You Just move on?

April 28, 2012 by

One of the biggest mistakes students taking GMAT practice tests make is spending too much time on quantitative problems.  This is especially true of problems they are unsure of how to solve.

Remember, the quantitative section of the GMAT asks you to complete 37 questions in 75 minutes.  This means that you have only two minutes per question.  That’s not much time as I am sure many of you already know.  Thus, it is important that you use your time in the most efficient manner possible.

While many test-takers feel they will not be able to complete the test in time, you should also keep in mind that the questions are designed so that it is possible to complete each one in an average of two minutes.  While some questions will take a little more or a little less time than this, you should never be spending over five … Read full post
