Working Smarter, Not Harder

by

What’s more valuable on the GMAT? Saving 30 seconds on a question that took you 2:30 to solve? Or 30 seconds on a question that took you 1:30 to solve? Trick question. Either way, you have the same amount of extra time to use on some other question. So with that in mind, take out a timer, pen, and paper, and let’s try out a fairly straightforward GMATPrep problem.

 

District

Number of Votes

Percent of Votes for Candidate P

Percent of Votes for Candidate Q

1

800

60

40

2

1,000

50

50

3

1,500

50

50

4

1,800

40

60

5

1,200

30

70

 

The table above shows the results of a recent school board election in which the candidate with the higher total number of votes from the five districts was declared the winner. Which district had the greatest number of votes for the winner?

 

(A)  1

(B)  2

(C)  3

(D)  4

(E)  5

Now before we work through the problem. Ask yourself a few questions about what you just did:

  1. How confident are you in your answer?
  2. How much time did you take to answer?
  3. Looking back on your solution, was there shortcut you could have used to eliminate some of the work you did?
  4. If so, what specifically about this problem allows you to use your shortcut?

At this point, hopefully you either did the shortcut for this problem or discovered what the shortcut might be. Let’s start with the long method. If I wanted to calculate the number of votes for each candidate, it would look like this:

District

Number of Votes

Total Number of Votes for Candidate P

Total Number of Votes for Candidate Q

1

800

480

320

2

1,000

500

500

3

1,500

750

750

4

1,800

720

1,080

5

1,200

360

840

Total

6,300

2,810

3,490

Twelve calculations later (ten products and two sums), we have all of our numbers calculated and can answer two questions:

  1. Who won the election? (Candidate Q)
  2. Which district had the most votes for that candidate? (District 4- answer D)

Let’s go back for a second though. Are there any calculations from above that we could have skipped? Let’s start by analyzing the first question from above. Who won the election?

Should You Take a GMAT Prep Course?

by

should i take a gmat courseIn my 9-session courses, all students are invited to try the first session for free. At the end of that trial session, one or more students invariably ask me, do I need to take this course to get a good score on the GMAT?

In a word, no. In fact, I scored a 760 on my first attempt, and I didn’t take a prep course. But then again, I devoted my lunch hour to studying for more than two months straight. Every. Single. Workday.

I’d like to think I’m a smart guy, but even so, there’s no way I could have scored a 760 without putting in significant study time. That is true for 99.99% of the GMAT-taking population, prep course or no. If you want to get the most out of my class, be prepared for an hour of homework every day for the duration of the course.

Has this happened to you? You’re reviewing a practice test, and you look at a question you got wrong. “That was just a stupid mistake,” you say, “I should have gotten that one right. I’ll get it next time.” Read more

My Timing Is Killing Me

by

gmat timingI’ve written a lot “ and you’ve read a lot “ about timing already, but I want to address something that I’ve been hearing lately from students particularly those who have been studying for a while and are really struggling to make progress on practice tests.

My best timing was on my very first practice test

I’ve spoken with a few students lately who’ve told me that they felt more comfortable with the timing before they started studying all of this stuff. How is that possible?

Actually, it’s fairly common. Here’s what happens: on your first practice test (before or shortly after you started studying), you know what you don’t know and so it’s much easier to let go of the too-hard questions. Once you start studying, you’ll see something and think, Oh, I studied that! I can get this one! But it turns out that one is still too hard only, this time, you won’t let go when you should. Do that a few times and the whole situation snowballs: you realize you’re behind on time, you start to panic and rush, that causes careless mistakes. Then you get stuck on another because you feel like you’re getting a bunch wrong so you don’t want to get this one wrong too now you’re wasting even more time, and then the section ends with a bunch of guesses or even blank questions.

I’m fine with OG / untimed / with shorter problem sets

I’m sure it’s no surprise to you that you’re better when the timer isn’t ticking. We all are. Unfortunately, the real test is timed, so our untimed performance doesn’t matter. Lots of people also discover that everything’s fine when doing sets out of the Official Guide, especially shorter problem sets. This, again, is to be expected “ the OG isn’t adaptive (so you aren’t getting harder questions when you do well), and it’s easier to keep track of your global time for 5 or 10 questions rather than 37 or 41.

So what do I do?

The Reality of Doing

by

Many a true word is said in jest.—I don’t know, but I heard it from my mother.

Folks don’t score as well as they should on the GMAT for a variety of reasons. One major reason for this is that folks worry about the wrong thing.  They worry about what they know, but they should be worrying about what they do.  They should worry about the reality of doing.  As an athlete does physically and as a method actor does mentally.  (Wait for it.)

gmat eyeThe GMAT is an aptitude test, not a knowledge test.  It tests the same logic system throughout—in both the math and the verbal.  In both sections, the modus operandi is to be specific, don’t assume, and don’t rationalize.  Be more precise than in life; notice the exact meaning of the words.  It takes classes three weeks to open their third eyes and notice the difference between precision and hoping.  Second, no outside knowledge or assumptions are allowed.  However, the hardest part for GMAT test takers is not to rationalize.  The questions ask what MUST be true, not what COULD be true by adding opinions.  Folks want to demonstrate the depth of their thoughts, but the questions ask what must follow—-so, whatever you do, don’t think. . .much like in life.  Just do.

A student, who was accepted to both Harvard and Stanford, once said to me, The funny thing about the GMAT is that the math is the verbal and the verbal is the math.  Because it is one logic system, there is a truth to this—the verbal is the math because you must not only be as precise as, but also as systematic as you are in quantitative work.  On the other hand, the math revolves around noticing exactly what the words say, as well as and reading and writing with symbols.  Doing the arithmetic and algebra is the moral equivalent of reading English—it is taken for granted and not tested per se.  This is a double edged sword. Folks are ruined because they concentrate on challenging math topics but their shoddy mechanics cost them at least half a minute per problem.  That, however, is a separate reason for, and separate article about, why folks do not score as well as they should.

Okay… I’ve Decided To Postpone For a Year

by

Recently, we talked about what to try if your deadlines are rapidly approaching and you don’t yet have the score that you want. I’d like to talk about next steps for those of you who decide to postpone your exam and possibly your b-school applications.

I didn’t actually decide “ I just didn’t get the score I wanted

postpone gmatFirst, a pep talk. You always have a choice. You could, for example, choose to apply this year but lower your standards in terms of where you apply. In fact, if you fall into certain categories, this may be better than waiting a year to try to get into a better (or, at least, higher-ranked) school. Let’s say that you’re being groomed to take over a family business. The current CEO is getting older. The business is well-established and fairly regional, so actually the best thing might be to get a degree from a respected (but not necessarily top) school in the same geographic region as the company headquarters.

On the other hand, let’s say that’s NOT you “ in your case, you’re only willing to spend $100,000+ if you can get into a top-fill-in-the-blank school (top 5? top 10? top 20?), and your current GMAT score is probably going to hold you back. In that case, postponing for a year may be the way to go. Any helpful friends or family members who say, Hey, I thought you were applying to business school! can be told, It’s actually a smarter career move to wait until next year. They don’t need to know that the GMAT had anything to do with that decision.

Beware Shortcuts in Thinking

by

gmat thinkingWe’ve heard the expression Don’t reinvent the wheel. There is no need to start from scratch every time you undertake a task.  The same reasoning applies in many ways to GMAT problems.  In fact, this logic is exactly why doing practice problems is a valuable tool for improving your GMAT score.  If you have seen a similar problem before, you will probably have a jumping off point for that problem on the actual GMAT.

While focusing on efficiency is important on the GMAT, in some cases it can be problematic to rely on traditional rules of thumb.  The GMAT is good at finding and testing the exceptions to rules that apply in many cases.  For example, the adage it takes two equations to solve for two variables is not true in all cases.

One common shortcut of thinking is the assumption that to show the converse of a statement you need exactly the opposite information.
That is: If in order to prove x, I must know y and z are true then in order to prove the opposite of x I must know that y and z are false.

5 Simple Math Tricks for Faster Computations

Manhattan Prep GMAT Blog - 5 Simple Math Tricks for Faster Computations by Joe LuceroDid you know that you can attend the first session of any of our online or in-person GMAT courses absolutely free? We’re not kidding! Check out our upcoming courses here.


For every five hours of studying combinatorics-type questions, the average GMAT student increases their chances of being able to correctly answer a question type that is found only on the very difficult end of the GMAT spectrum. Meanwhile, the same student will have to compute hundreds of basic computations without the aid of a calculator. For students who know how to quickly do these computations, they are rewarded with extra minutes that can be spent double-checking their work and critically thinking about whether their answers make sense. As BenGMAT Franklin might say, a second saved is a second earned on the GMAT, but it doesn’t matter if those extra seconds come from being faster at doing combinatorics questions or quicker at computations. So check out these five math tricks, learn the ones that you like, and practice them daily to give yourself some extra time to finish off that 37th and final Quant question.

Note: like everything else on the GMAT, being able to do something and being able to do something QUICKLY are two different tasks. If you like any of the following math tricks, make sure you know it inside and out before you try using it during your test. Read more

This Fraction Problem Is Harder Than It Looks

by

I’ve spoken with multiple students lately who received a disappointing (lower than they were expecting) score on the Quant section and who all said that the Quant felt relatively easy or straightforward. How is that possible?gmat factions

First of all, thinking that a test like the GMAT is easy is actually a warning sign: things probably are not going very well. If the test was going very well, then you’d be seeing some seriously hard—next to impossible—problems.

Second, the test writers are phenomenal at writing questions that don’t seem all that complicated but are in fact your worst nightmare. My worst nightmare is not an impossible question—I know I can’t do it, so I just pick and move on. My worst nightmare is a question that I think I can do, and I spend a decent chunk of time doing it, and then I get it wrong anyway—even though I’m sure I got it right! Read more
