For GMAT instructors and number enthusiasts, yesterday was a banner day – on April 25, 4/25, both the month and the day (4 and 25) were perfect squares (2-squared and 5-squared). And with that in mind, let’s take a look at some properties of squares that can help you better solve exponent questions on the GMAT.

The sports news story du jour is an amazing one – 14 year old Tianlang Guan spent yesterday not doing math homework (like you presumably are) or household chores like a normal 14-year old on a Thursday. He spent it shooting an incredibly impressive round at the Masters, arguably the world’s most prestigious golf tournament. His score of 73 beat the defending champion by two strokes and kept him in the hunt for another day. And it should also have taught you a lesson about the GMAT:
It’s the first week of the Major League Baseball season, a sure sign of springtime and a massive celebration in most MLB cities as fans begin the season with new hope and a spirit of outdoor community. And if you’re watching, it can provide you with valuable insight to your forthcoming GMAT appointment. Because like most elite pitchers, the GMAT has a nasty curveball.
It’s the last Friday in March, and all good things must come to an end, including Hip Hop Month in the GMAT Tip of the Week space. But if you’ve been reading along with us all month, hopefully your iPod or car stereo has become your best study partner. While you’re driving home from work and the Kanye/Good Music track “Clique” comes on, you might hear Jay Z’s verse and immediately start thinking about sequence problems:
As Hip Hop Month rolls on in the GMAT Tip of the Week space, we’re reminded that small nuances in the ways that GMAT questions are structured can have big consequences for test-takers. So who would be a more fitting man to teach that lesson – what’s small can have big consequences – than Biggie Smalls?
As loyal readers of this space will know, if it’s a Friday in March that means it’s Hip Hop Month for GMAT tips, and the US government sequester will not slow us down! Although it may inspire us. As the government careens toward desperate austerity measures, frugality is in the air, both in Washington and on your radio. Which is good news – let’s pop some tags and talk about how going to the Thrift Shop, Macklemore style, can help you crush GMAT Data Sufficiency.
It’s Oscar weekend here in Los Angeles, and that can only mean one thing:
The winner is…your GMAT verbal score.
How can this year’s Academy Awards improve your performance on GMAT Sentence Correction? Let’s look at the odds-on favorite to win Best Picture, Argo. The title alone, Argo, brings up two important points about GMAT Sentence Correction:
In a Valentine’s Day surprise yesterday, the standard Thursday Veritas Prep staff meeting was crashed by a lovable intruder. Cookie Monster – yes, the one-track-minded carnivore from Sesame Street – barreled into the meeting with a singing telegram for our Director of Admissions Consulting and Worldwide GMAT Instructor of the Year, Travis Morgan. Bearing a message of love and his standard message of “me want cookie”, he also reminded the GMAT staff of why Cookie Monster would fail miserably at the GMAT:
As we’ve reached the midpoint between buzzing over Beyonce’s “Crazy In Love” intro over the weekend and Valentine’s Day next week, love is in the air. Which is a good thing in most respects, but can be a dangerous one on the GMAT. You might well say that one of the most common mistakes that test-takers make on verbal questions is “love at first sight”.
If you’re like many this weekend, you’ll do some gambling on the Super Bowl. Whether it’s a squares pool at a Super Bowl party, some prop bets in Vegas, or a mayoral contest between the chief executives of Baltimore and San Francisco (Rice-a-Roni against some DVDs of The Wire?), you’ll have opportunities to either win or lose based on probability. So here’s a tip that can help you on both football bets and the GMAT:
If you’re a regular reader of this corner of the Veritas Prep blog, you should know that we like to take Friday mornings to identify something newsworthy and relate it to the GMAT. But this week, the trivial-enough-to-blog news cycle has seemed to take a break. Manti Te’o is old news, the NFL playoffs are in their bye week before the Super Bowl… When the world takes a break, what’s a GMAT blogger to do?
One of the more-dreaded types of GMAT Problem Solving questions is the “must be true” question with three statements; these questions often look like:
If 20x = 49y, which of the following must be true?
I. x > y
II. x2 > y2
III. x/7 is an integer
For many GMAT test-takers, one of the most challenging tasks on the exam is that of weeding through the clutter on Sentence Correction questions to arrive at an actionable decision point. So many Sentence Correction questions involve a lot of dense language and not-altogether-enjoyable subject matter, and as a result students spend a lot of time spinning their wheels trying to even get going.
Many test-takers lament the very presence of Sentence Correction questions, feeling overwhelmed as they study grammar rules and still overwhelmed as they look at practice questions and cannot determine where to start. Sentence Correction can be daunting – the English language is far from binary in its usage (“I before E except after C”…and even that has a bunch of extra caveats), and the questions themselves are specifically designed to make finding your Decision Points difficult.
Baby, it’s cold outside. Pretty much no matter where you are while you read this, it’s cold right now (even here in Los Angeles), and whether it’s by blankets, Starbucks holiday drinks, or thermal underwear, you’re probably hoping to warm up. Which is actually good advice for the GMAT, too, just in a slightly different way.
As Twitter has confirmed, the real winner in this week’s U.S. Elections was Nate Silver, the statistician behind fivethirtyeight.com and the prognosticator who called nearly every national race correctly, save for one senate race in North Dakota. Famously, he predicted each state’s presidential race correctly and he’s risen to prominence with a role on the New York Times and with his new book “The Signal and the Noise.” So with Nate Silver taking statistical analysis to heights that Moneyball only hoped to, it’s only fitting that we close this week by summoning our inner Silver and taking a statistical dive at GMAT questions.
Polling isn’t new, nor is statistical analysis. So why is Nate Silver so much more successful than others when it comes to using statistics to project outcomes? If we understood completely, we’d be writing a different article for a lot more money on a more-heavily-trafficked blog, but the layman’s answer is largely that he takes time to determine which statistics are most relevant to the outcome, and focuses his energy on those. And that’s what you should do when you analyze your GMAT practice tests and consume information about the GMAT – cut to the most meaningful statistics and focus your energy there.
So it is upon us. The much-anticipated final Jobs Report before the 2012 Presidential Election has been released, and its results will fuel debates all weekend and can have a significant impact on your GMAT verbal score if you pay attention to the arguments that surround it.
Here’s what happened – the American economy added 171,000 new jobs, beating economists’ predictions by a healthy margin (good news?) but the unemployment rate ticked up a tenth of a point from last month’s figure (bad news?). And in full GMAT Critical Reasoning mode, pundits and political representatives immediately began using those statistics to draw unsupported conclusions. Check out these Critical Reasoning style Weaken questions you could make from today’s arguments:
Happy Halloween Weekend, readers (and, yes, we do find it odd that for this generation Halloween now spans several days and seems to have more relevance for 20-somethings than does pretty much any other holiday, but we’re not complaining).
As you put the final touches on your Halloween costume for the weekend – our ever-on-the-pulse-of-costume-popularity coworker, Jason (2010 – Antoine Dodson; 2011- Angry Birds. Every year he’s ahead of the curve on “most popular costume”) is going as Gangam Style – it’s not a bad time to keep your eyes one one of the next hallmarks of the fall-winter calendar, Round Two Application Deadlines. And here’s where the two coincide:
There’s a lot you can learn about your GMAT preparation everywhere you look… even in the cutthroat world of American politics. Yes, even watching two Harvard grads snarl at each other can help you become a better GMAT student and, ultimately, a higher score on the exam.
If you watched the U.S. Presidential Debate this week, you hopefully saw a lot of similarities between you and the candidates:
Within hours of the Detroit Tigers’ blown Game 4 lead against the Oakland A’s, ensuring a fifth and decisive game of the American League Divisional Series, devastated (and exhausted) Detroiters started watching their Facebook and Twitter feeds fill with an internet meme that would prove prophetic:
Justin Verlander the Game Five pitcher, with the slogan “Everybody Chill Out…I Got This”
And “got this” he did, pitching a complete and dominant game, shutting out the A’s and seemingly inspiring run support from what had been dead bats all series. And in doing so, Verlander showed you how to raise your game for the GMAT. He made it known loud and clear – not necessarily from his words but from his actions, demeanor, and commitment, that he was finishing the job no matter what — he wouldn’t hand the ball off to a relief pitcher if there were any way to avoid it.
It’s Friday, so if you’re in the GMAT’s general demographic range (20-something, college grad, young professional) there’s a good chance you’ll hit a bar tonight. And there you may have a chance to witness (or experience) an age-old phenomenon that just may help you avoid a common pitfall on the GMAT:
If you’re like many GMAT test-takers trying to bump up against that “glass ceiling” of 700, you may be frustrated that you keep studying and drilling math concepts and problems but you’re still not improving on Data Sufficiency questions. Does that sound like you?
If so, there’s a reason. While Data Sufficiency both involves math and appears on the Quantitative Reasoning section of the GMAT, it’s not simply a math question. It’s a logic puzzle that hinges on math concepts, and your ability to embrace that subtle difference might just be the difference between reaching your goal score and falling short. For example, consider a few Data Sufficiency questions that employ Geometry principles – as Geometry tends to be among the topics for which students study the most “stuff”.
If the political convention season had one theme in its most-talked-about speeches, it was essentially this: interviewing presidents. Last week, Clint Eastwood owned the Twittersphere with his interview of an invisible Barack Obama, who responded to those questions with exactly zero words (largely because he wasn’t actually there).
And in this past Wednesday’s most-Tweeted-about speech of the DNC, Bill Clinton talked about a question that he’s frequently asked in interviews, and one of his signature lines of the night was his one-word response: Arithmetic.
If Clint Eastwood went ahead and made anyone’s day last night, it was probably Jon Stewart’s or Stephen Colbert’s, as the legendary film star stole the show at last night’s GOP convention and launched himself to the top of social media trend charts. It can be debated whether Eastwood’s unique speech hit or missed the mark; whether those that invited him were pleased or disappointed with his performance; or whether Saturday Night Live’s forthcoming impression will be one for the ages.
But what cannot be debated is this – by spending some time holding a conversation with an empty chair, Clint Eastwood taught you an important GMAT test-day lesson:
With this week’s Lance Armstrong news and this blog’s history of rolling cycling news into GMAT tip posts, it’s only natural that today’s GMAT tip will involve that news. We’ll reserve judgment on the Armstrong case, specifically, but let’s use the situation to talk about GMAT Critical Reasoning and the way that it often uses statistics in arguments to assess your ability to think critically.
Consider an argument such as:
A test to denote the presence of a particular performance enhancing drug is known to be accurate in 95% of its cases. A certain athlete’s sample has tested positive for the presence of that drug. Therefore, by virtue of this test, we can conclude that it is far more likely than not that the athlete used that drug.
One of this weekend’s most popular barroom debates will be this: Is Usain Bolt the greatest sprinter of all time? The greatest Olympian of all time? The Muhammad Ali for this generation?
If you missed it, Usain Bolt tacked on another gold medal last night, winning the 200 meters in 19.32 seconds having eased up to celebrate in the waning meters. While this on-the-run celebration certainly cost him an Olympic record (19.30) and potentially even a world record (19.19), it didn’t cost him the race as he remained ahead of teammate Yohan Blake en route to the win. In doing so, Bolt laid claim with his back-to-back 100 AND 200 meter titles to his place as the Ali-esque Greatest of All Time. And, inadvertently, he may have helped you better understand how to perform on the GMAT with regard to pacing, as the 200 meter dash provides a nice parallel to how you should pace yourself on the GMAT.
This week’s GMAT Tip of the Week comes from David Newland, a Veritas Prep GMAT prep instructor based in Boston.
There is a show on ABC on Monday nights that — in my opinion — has almost no redeeming qualities. However, this show does demonstrate a very important facet of data sufficiency. The show is called “The Bachelor” and it features one unmarried man, the bachelor, who claims to be tired of being single and looking to get married. The process of selecting a bride is conducted like a game show. Dozens of women are brought out and the bachelor slowly sifts through them eliminating them or keeping them around by giving them a rose. At the end the bachelor proposes to the chosen woman and they live happily ever after…that is until a few months later — surprise, surprise — we learn that the relationship did not work out. What could have gone wrong? Isn’t this the way all successful relationships begin — on a game show?
Back in February, the entire sporting world succumbed to (Jeremy) Linsanity. But, alas, the GMAT world was months away from the perfect Lin-guistic technique, using “Lin” as a Lintroductory term for “Integrated Reasoning.” So it was with great fanfare this week that Jeremy Lin leaped right back to the top of the news wire, signing with the Houston Rockets and not only creating an opportunity for a fantastic pun with Lintegrated Reasoning, but demonstrating — to the dismay of the world MBA capital, New York City – how to think strategically on Integrated Reasoning questions.
Many IR questions will involve the use of not just math, but “strategic math.” The Houston Rockets’ offer sheet to Lin – a sheet that could have been matched by the Knicks – wasn’t entirely noteworthy in its size. $25 million over 3 years isn’t at all an unconscionable contract for a starting point guard, and Lin is a special case in his marketability. Overseas broadcast rights, jersey sales, ticket sales – Lin has the potential to recoup that investment quickly.
On the GMAT, Critical Reasoning problems often ask you to strengthen a conclusion, weaken a conclusion, or determine an assumption necessary for the conclusion to hold true. In any of these cases, it is of prime importance that you know exactly what the conclusion is saying; otherwise, it can be easy for your answer choice to miss the mark.
It’s therefore important to ensure that you correctly identify the conclusion of the argument, and to make doing so a priority. There are four clues to determine the conclusion of a Critical Reasoning argument, any of which should help you determine which statement is the argument’s conclusion:
1) Conclusion language such as “thus” or “therefore”
2) A call for action, such as “they must…” or “we should…”
Now that Integrated Reasoning is here to stay on the GMAT, it’s time to, as Outkast would say, “hush that fuss” about how to avoid IR for your fall application or why IR is a new behemoth worthy of fear. As we’ve mentioned many times in this space, IR isn’t as “new” as the hype would suggest. And to conquer it, it’s probably best to heed some other advice from Outkast and specifically from Andre 3000 (not his SAT score) in the song “Roses”:
If you’ve spent more than ten minutes researching the GMAT, you probably know that it’s a computer-adaptive test (CAT). As the name suggests, the GMAT is administered via computer, and it adapts to you based on how you do on each question. By “adapts,” we mean that it decides what question to show you next based on how you’ve done on your previous questions. At any given point in the exam, the test has a best guess as to your ability level, and it keeps serving questions to try to get an even more accurate read on you.
A more simplistic way to phrase that last statement would be: “Get a question right, and the next question gets harder.” But what’s “harder” to one person may not be for another person. The GMAT has a humongous (that’s the technical term) bank of questions, and each one is effective teasing out differences among test takers around a certain ability level. A given question might be too basic to tease out the difference between 700- and 750-level test takers, while another might be too advanced to tell apart 580- and 630-level test takers. When we say that a question is “easier” or “harder” than the last, that’s what we mean.
Today Veritas Prep GMAT prep instructor extraordinaire David Newland provides some insights on overcoming anxiety on test day. Read on… This is really interesting advice that can significantly improve your performance and help you reach your maximum potential on the GMAT!
For the last 15 years a wave of laughter has swept across one of the largest countries in the world. Why are so many people in India laughing? Is it because they have just spoken to some American and are amazed at the crazy way that most Americans speak “English”? No. The laughter is coming from “laughing clubs” where people practice “laughter yoga.” Now maybe those of you who have not heard of laughter yoga are laughing a bit at the whole concept… That would be music to the ears of Dr. Kataria the founder of laughter yoga.
Repeatedly in this space, you’ve read the theme “Think Like the Testmaker,” an important mantra for success on the GMAT. Also important – knowing precisely what that means, and what it doesn’t. The Veritas Prep emphasis on “Think Like the Testmaker”:
– DOES NOT mean that you somehow need to play mindreader, that GMAT questions are subjective and if you don’t share the testmaker’s opinion or style you’ll get questions wrong. GMAT questions are binary – there are four incorrect answers and one correct answer every time. Even if a question asks you to select “the best” answer, you’re really trying to select “the correct” answer. The other four will be fatally flawed.
If you’re reading this post in preparation for the GMAT, you are in luck:
You’re taking the Integrated Reasoning section.
After a few months of handwringing over whether to rush to take the “old” GMAT or to instead take the “new” GMAT, those taking the test after today have just one choice: take the GMAT. Which happens to include Integrated Reasoning. Queme los barcos.
With just over a week to go until the debut of the Integrated Reasoning section, “Integrated Reasoning” Google searches are up just about as much as Facebook stock is down. With that in mind, let’s discuss the Graphics Interpretation question type through the lens of the stock market to show you how the creators of the GMAT will use your mind’s natural tendencies against you.
Do you have an iPhone? If so, pull up the “Stocks” app and look at the graph at the bottom of the page. What you see will look something like this:
Sun Tzu is famous for saying, in The Art of War, “know thy enemy, know thy self” (a loose translation, but that’s the famous quotation that has lasted centuries). And while at Veritas Prep we hesitate to call the authors of the GMAT “thy enemy,” we still advocate that you learn to Think Like the Testmaker, much as Sun Tzu would advise, and to think about how well the testmaker knows yourself.
Know this about “thy enemy” — the makers of the GMAT will admit that theirs is a test of “higher order thinking”, of your ability to think critically, solve problems efficiently, and otherwise demonstrate not merely that you have knowledge but that when you do have knowledge you can leverage it to greater gain. For this reason, the test is obligated to use tricks, shortcuts, and partial knowledge against you if that’s all you bring to the table on harder questions; at some point in the 500s/600s, the test has to determine not just “who studied” but “who can really think and problem solve”. And for that reason, a little bit of knowledge is a dangerous thing.
Read that sentence from the title again (please…in honor of Mothers Day we should certainly mind our Ps and Qs!): Colorless green ideas sleep furiously. Does that make any sense?
Not at all, but grammarians have to admit that *grammatically* it’s not a flawed sentence, in that it proceeds with Adjective, Adjective, Plural Noun, Plural Verb, Adverb. This sentence, coined by Noam Chomsky in his 1957 book Syntactic Structures, shows the necessity in language of not merely grammatical correctness, but logical meaning as well. And as you’ll note, this concept of “logical meaning” is one that has become increasingly common in these GMAT-themed blog circles of late, and one that has traditionally appeared on this blog in years past. Consider another, more GMAT-relevant sentence:
On the GMAT, Data Sufficiency questions can be tricky. But perhaps most frustrating about Data Sufficiency questions are those that somehow trick you when, upon further review, they gave you absolutely everything you needed. When you look back at them, you can’t believe that you got them wrong – but you should also notice patterns in why you did. One common way that an in-hindsight-pretty-straightforward question can be extremely challenging involves the “hiding” of pertinent information in the question stem itself, where the testmakers know that you’re apt to read quickly in your haste to get to the statements. Consider the question:
If xy < 0, is x/y > z?
(1) xyz < 0
(2) x > yz
As you study for the GMAT, it is important that you recognize that the GMAT is not a test of memory or knowledge, but rather of higher-order thinking, problem solving, and true understanding. If you’ve begun studying at the memorization/knowledge level, you may already be appalled at the title of this post (“Being! It’s wrong…it’s wrong!”). But that title – which employs correct usage of “being” – should indicate a better way of studying for a reasoning-based test. In this post, we’ll explain how.
First things first: Dr. Lawrence Rudner is considered by most to be the guru of the GMAT. He oversees the administration of the GMAT for the Graduate Management Admissions Council, shaping the scoring algorithm and the direction of question creation and implementation. So as you aspire to “Think Like the Testmaker” to fully understand the GMAT and how to succeed on it, in a way you’re hoping to think as much like Dr. Rudner as possible. Hopefully you learned in high school and college that the topics most favored by your professor were the most likely to appear on the exam; similarly, on the GMAT, if you can understand how questions are written and what they are trying to assess, you can become a much more effective studier and examinee.
