I’ve been speaking with a lot of students in this position recently “ welcome to December. Most second round deadlines are rapidly approaching and some students, unfortunately, don’t yet have the score they want in order to apply. What to do?

What you CAN’T do

There are some things you can do “ but we can’t expect miracles either. If you tell me that your test is in less than 2 weeks and you need to improve your score by 100 or more points, I’m going to (gently) tell you that such a goal is unrealistic. I’m not going to discourage you from going for it (it doesn’t hurt to try), but you should also start examining your other options are. These could include accepting your lower score, changing the schools to which you apply, or postponing your candidacy to a later round or a later year. Some people, thinking through this, actually end up deciding that they’d rather wait a year anyway and take their time with the whole application process.

Last time, we took a look at a Comparisons problem; in today’s article, we’re going to examine another one. This question is from the free problem set included in the new GMATPrep 2.0 version of the software. Try it out (1 minute 15 seconds) and then we’ll talk about it!

*  In Holland, a larger percentage of the gross national product is spent on defense of their coasts from rising seas than is spent on military defense in the United States.

 

(A) In Holland, a larger percentage of the gross national product is spent on defense of their coasts from rising seas than is spent on military defense in the United States.

(B) In Holland they spend a larger percentage of their gross national product on defending their coasts from rising seas than the United States does on military defense.

(C) A larger percentage of Holland’s gross national product is spent on defending their coasts from rising seas than the United States spends on military defense.

(D) Holland spends a larger percentage of its gross national product defending its coasts from rising seas than the military defense spending of the United States.

(E) Holland spends a larger percentage of its gross national product on defending its coasts from rising seas than the United States does on military defense.

I think this one follows nicely from the conversation that we had last week. We’ve got another comparison structure, we’ve got an entire sentence underlined, and yet there are also some differences here.

I’ve got a fascinating (and infuriating!) GMATPrep problem for you today; this comes from the free problem set included in the new GMATPrep 2.0 version of the software. Try it out (1 minute 15 seconds) and then we’ll talk about it!

*  Unlike computer skills or other technical skills, there is a disinclination on the part of many people to recognize the degree to which their analytical skills are weak.

 

(A) Unlike computer skills or other technical skills, there is a disinclination on the part of many people to recognize the degree to which their analytical skills are weak.

(B) Unlike computer skills or other technical skills, which they admit they lack, many people are disinclined to recognize that their analytical skills are weak.

(C) Unlike computer skills or other technical skills, analytical skills bring out a disinclination in many people to recognize that they are weak to a degree.

(D) Many people, willing to admit that they lack computer skills or other technical skills, are disinclined to recognize that their analytical skills are weak.

(E) Many people have a disinclination to recognize the weakness of their analytical skills while willing to admit their lack of computer skills or other technical skills.

 

I chose this problem because I thought the official explanation fell short; specifically, there are multiple declarations that something is wordy or awkward. While I agree with those characterizations, they aren’t particularly useful as teaching tools “ how can we tell that something is wordy or awkward? There isn’t an absolute way to rule; it’s a judgment call.

Now, I can understand why whoever wrote this explanation struggled to do so; this is an extremely difficult problem to explain. And that’s exactly why I wanted to have a crack at it “ I like a challenge. : )

Okay, let’s talk about the problem. My first reaction to the original sentence was: nope, that’s definitely wrong. When you think that, your next thought should be, Why? Which part, specifically? This allows you to know that you have a valid reason for eliminating an answer and it also allows you to figure out what you should examine in other answers.

Before you read my next paragraph, answer that question for yourself. What, specifically, doesn’t sound good or doesn’t work in the original sentence?

This week, we’re going to analyze a particularly tough GMATPrepSentence Correction question.

First, set your timer for 1 minute and 15 seconds and try the problem!

Research has shown that when speaking, individuals who have been blind from birth and have thus never seen anyone gesture nonetheless make hand motions just as frequently and in the same way as sighted people do, and that they will gesture even when conversing with another blind person.

A) have thus never seen anyone gesture nonetheless make hand motions just as frequently and in the same way as sighted people do, and that

B) have thus never seen anyone gesture but nonetheless make hand motions just as frequently and in the same way that sighted people do, and

C) have thus never seen anyone gesture, that they nonetheless make hand motions just as frequently and in the same way as sighted people do, and

D) thus they have never seen anyone gesture, but nonetheless they make hand motions just as frequently and in the same way that sighted people do, and that

E) thus they have never seen anyone gesture nonetheless make hand motions just as frequently and in the same way that sighted people do, and

Okay, have you got your answer? Now, let’s dive into this thing! What did you think when you read the original sentence?

This is a very tough problem; when I read the sentence the first time, I actually had to stop and try to strip the sentence down to its basic core, then figure out how the modifiers fit. Until I did that, I couldn’t go any further.

Most people don’t like weighted averages, and for good reason. The formula is complicated, and these often come in the form of story problems, which are hard to set up. We’re going to talk today about a couple of great little techniques to make these fast and easy well, easier anyway!

First, try this GMATPrep problem. Set your timer for 2 minutes. and GO!

*  A rabbit on a controlled diet is fed daily 300 grams of a mixture of two foods, food X and food Y. Food X contains 10 percent protein and food Y contains 15 percent protein. If the rabbit’s diet provides exactly 38 grams of protein daily, how many grams of food X are in the mixture?

 

(A) 100

(B) 140

(C) 150

(D) 160

(E) 200

Wow. I’m glad I don’t have to feed this rabbit. This sounds annoying. : )

I’ve got a fascinating little GMATPrep problem for you today. Try it out (1 minute 15 seconds) and then we’ll talk about it!

*  As the honeybee’s stinger is heavily barbed, staying where it is inserted, this results in the act of stinging causing the bee to sustain a fatal injury.

 

(A) As the honeybee’s stinger is heavily barbed, staying where it is inserted, this results in the act of stinging causing

(B) As the heavily barbed stinger of the honeybee stays where it is inserted, with the result that the act of stinging causes

(C) The honeybee’s stinger, heavily barbed and staying where it is inserted, results in the fact that the act of stinging causes

(D) The heavily barbed stinger of the honeybee stays where it is inserted, and results in the act of stinging causing

(E) The honeybee’s stinger is heavily barbed and stays where it is inserted, with the result that the act of stinging causes

I chose this problem because it addresses multiple tricky issues that are perhaps easy to hear “ if you have built a good GMAT ear “ but are difficult to explain or articulate. Anything that’s difficult to explain or articulate to yourself is harder to remember. It’s also easier for us to be fooled by our ears on such sentences.

Okay, let’s talk about the problem. My first reaction to the original sentence was: nope, that’s definitely wrong. Now, when the clock is actually ticking and I’m that confident, I don’t bother to try to explain to myself why, exactly, this one is wrong. I just cross off A and look for others that I can cross off for the same reasons I crossed off A.

Here, though, I hit a snag. When I went to the cross off anything else with the same mistake step there wasn’t a single word or location in the sentence on which I could concentrate.

As we discussed a few months ago, most schools are still determining how to use IR during the admissions process. A recent US News article reports on a new survey just released by Kaplan; the survey lends broader support to the anecdotal reports that we’ve been hearing from individual schools.

Kaplan surveyed 265 business schools, including 17 of the top 25, to find out how they’ve been using IR so far. A little over half are still figuring out what to do with the score, while roughly ¼ of the respondents indicated that they already consider IR important. Even in that last category, though, the schools are still determining how much emphasis to place on IR. US News spoke with Dawna Clarke, Director of Admissions at Dartmouth’s Tuck School of Business and while she does consider IR important, she also indicated that they’re still figuring out exactly how to use the scores in the absence of well-established historical data. In a nutshell: people aren’t quite sure yet what the data means or how much of an impact it should have on admissions.

Expect all of this to begin changing next year. Assuming that the data eventually establishes that the IR section does actually identify strong business school candidates, the schools will likely begin using IR more seriously during the 2013 admissions season (for those who are hoping to enter a program beginning in 2014). How heavily will IR weigh in the admissions decision? We won’t know that until we start to have better analyses of how useful the score is; if it turns out to be a strong predictor of b-school success, then IR is rapidly going to become a very important part of the GMAT.

Remember those times when you were sure you got the answer right, only to find out that you got it wrong? For a moment, you even think that there must be a mistake in the answer key. Then, you take a look at the problem again, you check your work, and you say, I can’t believe I did that! You knew exactly how to do this problem and you should have gotten it right, but you made a careless mistake.

What’s a Careless Error?

By definition, a careless mistake occurs when we did actually know all of the necessary info and we did actually possess all of the necessary skills, but we made a mistake anyway. We all make careless mistakes (yes, even the experts!); over 3.5 hours, it’s not reasonable to assume that we can completely avoid making careless mistakes. Our goal is to learn how to minimize careless mistakes as much as possible.

How Can We Minimize Careless Errors?

Isn’t the whole point of a careless error that we don’t know when we’re going to make them? They just happen randomly and we can’t control that!

Find the Assumption questions are very common Critical Reasoning question types. If you don’t yet know the general process for tackling Critical Reasoning problems, learn how before you keep reading this article.

Ready to try a question? Set your timer for 2 minutes and try this GMATPrep problem:

In a study conducted in Canada, servers in various restaurants wrote Thank you on randomly selected bills before presenting the bills to their customers. Tips on these bills were an average of three percentage points higher than tips on bills without the message. Therefore, if servers in Canada regularly wrote Thank you on restaurant bills, their average income from tips would be significantly higher than it otherwise would have been.

Which of the following is an assumption on which the argument relies?

(A) The Thank you messages would have the same impact on regular patrons of a restaurant as they would on occasional patrons of the same restaurant.

(B) Regularly seeing Thank you written on their bills would not lead restaurant patrons to revert to their earlier tipping habits.

(C) The written Thank you reminds restaurant patrons that tips constitute a significant part of the income of many food servers.

(D) The rate at which people tip food servers in Canada does not vary with how expensive a restaurant is.

(E) Virtually all patrons of the Canadian restaurants in the study who were given a bill with Thank you written on it left a larger tip than they otherwise would have.

Got your answer? Let’s start going through this one!

Step 1: Identify the Question

The question stem contains the word assumption, which is a pretty good clue that this is a Find the Assumption (FA) question. This question type always contains a conclusion and I know it’s important to find that conclusion. Also, if I can, I’m going to brainstorm any assumptions I can think of without taking too much time.

Recently, a new student asked me what he could do to get the most out of our class and his study time over the next several months. He’s not the first person to ask me this, but when I was responding to him, I realized that I really needed to write this down and share it with all of you. Many of you have heard me say these things in various forms in articles, blog posts, or forum responses over the years—but here they are in one place.

So, without further ado, the 2 biggest mistakes that people make when studying for the GMAT:

#1 Doing instead of Analyzing

Most people try to study for the GMAT in the same way they studied for school—and, for most people, that isn’t going to lead to a 700+. The GMAT is not a math test or a grammar test—really, it isn’t! It’s a reasoning test—and I’m not just referring to critical reasoning. The GMAT is really a test of how we think. If that’s not your primary focus when studying, you won’t get the best score you could get.
