A leading board member of AutoSnip Co., makers of an automated home haircutting system, recently stated that the company was in terrible shape and headed for a disastrous year. His concern was that, since the introduction of the AutoSnip III last year, calls to the customer service line have nearly doubled, indicating that people are very unhappy with the new product. Although it's true that it is the job of responsible board members to raise issues of concern, in this case the board member's analysis of the situation is mistaken. The customer service line handles not only complaints but also sales, and the majority of the new calls have been to place new orders.

What role do the two boldfaced selections play in the above argument?

A.The first provides evidence supporting the main conclusion of the argument; the second provides evidence supporting a conclusion that the argument opposes.

B. The first provides evidence, an interpretation of which supports the main conclusion of the argument; the second provides evidence supporting the main conclusion of the argument.

C. The first provides incontrovertible evidence opposing the main conclusion of the argument; the second provides evidence supporting the main conclusion of the...

### How to correctly use Pronouns and Antecedents in GMAT Sentence Corrections

Errors in pronouns—words like he, she, it, they, our, etc.—and antecedents—the words that the pronouns refer to—are among the most common errors in English Grammar. Take this sentence as an example:

Sentence A: I spoke to someone at the help desk, and asked what kinds of product returns the company allows; they told me that they only take unopened items.

This sentence wouldn’t set off any “grammar alarms” for the average reader and speaker of English; however, you, intrepid GMAT test-taker, need to be wiser than average and spot a couple of pronoun/antecedent errors, such as:

1. “They” and “their” are plural pronouns, and CAN’T be used as gender-neutral singular pronouns

One of the most frequently-committed grammar sins in every day speech is the use of “they” and “their” to indicate gender neutrality. Sentence A, above, says “I spoke to someone.” The sentence later says, “they told me,” and based on context it is clear that the “they” in question is the “someone at the help desk.” “Someone” is...

### Do you recommend practicing GMAT Verbal and Quantitative at the same time?

F1GMAT: Do you recommend doing Verbal and Quantitive at the same time or one after the other?

Knewton: You should study both at the same time!

Studying Verbal for a while, and then studying for Quant for a while might lead to high section scores in the short term, but this strategy is not as effective in the long run.

If mastering the GMAT were as simple as memorizing groups of facts, like memorizing all the U.S. states and then all the Canadian provinces, you could plan your studies sequentially. In fact, it would probably make sense to. However, memorization is not a big part of the GMAT (except for certain handy-to-know items like idioms and common squares): it’s much more important to build all your test-taking skills in combination.

Studying for the GMAT is like working your muscles – if you do a month of chin ups, and then a month of sit ups, the rippling shoulders and biceps you built up after the first month will have faded away by end of the second month. In GMAT terms, your Quant skills...

### GMAT Fractions - Don't get lost in the calculations

Have you wondered how writers can make a seemingly simple GMAT topic like fractions into time-consuming calculations. One strategy that GMAT test takers must adopt to simplify the calculations. For example

Dividing by 5 is the same as multiplying by 2/10. For example:

• 840/5 = ?

• 840/5 = 840*(2/10) = 84*2 = 168

Multiplying or dividing by 10’s and 2’s is generally easier than using 5’s. 90% of the time, fractions will be easier to perform arithmetic. Decimals are sometimes more useful when comparing numbers relative to one another, such as in a number line, but these questions are the exception. Even if given a decimal (or percent) looks easy, quickly convert to a fraction. Some common ones to memorize:

• 1/9 = 0.111 repeating

• 1/8 = 0.125

• 1/7 = ~0.14

• 1/6 = 0.166 repeating

• 1/5 = 0.20

• 1/4 = 0.25

• 1/3 = 0.333 repeating

• 1/2 = 0.5 repeating

Note: Multiples of these, such as 3/8 (0.375) are also important to remember, but can easily be derived by multiplying the original fraction (1/8 * 3 = 3/8 = 0.125 * 3 = 0.375)

Denominators are super important. A denominator of a reduced fraction with a multiple of 7 will not have a finite...

### 5 Steps for GMAT Data Interpretation

1. Read the labels first. Mentally categorize each graph, chart and table. (EX: “This is a graph showing the change in the price of gas per gallon over the course of one year.”) Do not just skip the statistics entirely and go straight to the question! While you may think this will save you time, it actually significantly decreases your accuracy.

Data Interpretation questions are like an open-book test. You wouldn’t skip a Reading Comp passage, so don’t skip the data. Make sure you read every tiny piece of writing on or near the data, including titles, the labels for the x and y-axes, column names, and even footnotes. Scroll down to make sure you’ve caught everything.

2. Note the units. Once you understand the labels, take special care to note the units (mph, m/sec, cm2, etc.). Are we dealing with seconds, minutes, or hours? Does one graph represent the month of June, while the other graph represents the entire year? The units may change from graph-to-graph or chart-to-table. Especially note any given information about percentages, as DI questions frequently require you to work with...

### Top 10 GMAT Problem Solving Tips

The Problem Solving (PS) section of the GMAT may not be as quirky as the Data Sufficiency section of the test – but that doesn’t mean you don’t need to study for it! PS questions require more “straight math” than Data Sufficiency questions; in other words, they’ll probably be more like the questions you’re used to seeing on high school and college math tests. The best way to study? Master the basic concepts from geometry, algebra, statistics, and arithmetic — then check out these 10 helpful tips!

1. Make sure your fundamentals are strong.

The GMAT doesn’t allow you to use a calculator—which means you need to be quick and accurate with basic calculations. Be able to multiply and divide decimals. Know common higher powers and roots. Have fractions down to a science: Knowing right away whether 3/8 is less than 5/12 will mean you have more time later to work on more complicated calculations.

2. Choose numbers wisely.

Even questions that don’t contain variables can still be tackled by choosing numbers wisely. For example, if a question asks you about “a multiple of 6,” it’s probably quicker...

### Set A consists of integers -9, 8, 3, 10, and J; Set B consists of integers -2, 5, 0, 7, -6,

Set A consists of integers -9, 8, 3, 10, and J; Set B consists of integers -2, 5, 0, 7, -6, and T. If R is the median of Set A and W is the mode of set B, and R^W is a factor of 34, what is the value of T if J is negative?

(A) -2

(B) 0

(C) 1

(D) 2

(E) 5

Solution

This problem demonstrates a helpful note about statistics problems – quite often the key to solving a stats problem is something other than stats: number properties, divisibility, algebra, etc. The statistics nature of these problems is often just a way to make a simpler problem look more difficult.

Here, the phrase “factor of 34? should stand out to you, as there are only four factors of 34, so you can narrow down the possibilities pretty quickly to 1, 2, 17, and 34. And because the number in question must be an exponential term that becomes a factor of 34, it’s even more limited: 2, 17, and 34 can only be created by one integer exponent – “itself” to the first power.

The base of that exponent is going to be the median of Set A, and because we know that the median of Set A will be 3 (a negative term for variable J means that 3 will be the middle term), the question becomes that much clearer. 3^W can only be a factor of 34 if it’s set equal to 1, and the only way to do that is for W to be 0. REMEMBER: anything to the power of...

### GMAT Sentence Correction Strategies - Use Logic

The single-most crucial type of Sentence Correction error, Modifiers, Comparisons, and Verb Tenses all share one thing in common: you do not need to be an expert editor to recognize that this sentence is illogical! The introductory phrase in this sentence, “the single-most type…” is clearly meant to describe one item, but the rest of the sentence lists three. This does not make logical sense! Technically you’d call this a modifier error, in that the modifying phrase to begin the sentence – recognizable because it begins the sentence, is separated by a comma, and does not include its own subject and verb (note: these aren’t essential characteristics of any modifier, but they are one surefire way to identify a commonly-occurring type of modifier in which SC errors often crop up) – does not logically modify the noun that follows.

If you want to get really technical, it is an appositive modifier (a noun phrase used to describe another noun), but the GMAT will never require you to describe the...

### How to score well in GMAT Number properties?

GMAT Number properties may sound scary, but they just constitute elementary mathematical principles. You probably know most of these principles by memory; if not, you could easily execute a calculation to ascertain them. The best option, though, is to study these principles enough that they seem intuitive. The GMAT Quantitative section is all about saving time; making number theory second nature will definitely save you some valuable seconds.

1.Odds and Evens

Addition

Even + even = even (12+14=36)

Odd+ Odd = even (13+19=32)

Even + Odd = odd (8 + 11 = 19)

To more easily remember these, just think that a sum is only odd if you add an even and an odd.

Multiplication

Even x even = even (6 x 4 = 24)

Odd x odd = odd (5 x 3 = 15)

Even x odd = even (6 x 5= 30)

To more easily remember these, just think that a product is only odd if you multiply two odds.

Example Question

If r is even and t is odd, which of the following is odd?

A. rt

B. 5rt

C. 6...

### How to identify Style or Tone in GMAT Reading Comprehension

One question type you are bound to encounter on the GMAT Reading Comprehension is a style or tone question. Style and tone questions are particularly rare because most of the passages will be informational articles with neutral tones. For example, it would not be very challenging if you were asked to identify the tone of a passage about the many types of metamorphic rock - such a passage would surely be neutral.

The tone of any given passage is the author’s emotion or feeling, usually towards his subject. An author’s style is the particular way he uses language to reflect his unique authorial voice. Most style or tone questions will include the words “attitude,” “tone,” “style,” “feeling,” etc. A typical question of this type might look like this:

• The author’s attitude toward global warming might best be described as which of the following?

• Which of the following best describes the tone of the passage?

• Based on the statements in lines 43-46, which of the...

### 4 Tricks that will Keep you focused on your GMAT Reading Comprehension

GMAT Reading Comprehension passages are complicated and boring texts that will test your concentration and stamina. It is easy to lose your focus after an energy draining AWA and Math section. Most GMAT test takers will start to zone out at this stage and will just stare at the screen, re-reading the same sentence again and again. This is a sure shot step to crash your GMAT 700+ dream.

Follow these four preparation and test day tricks and you will learn to keep your focus for a long duration of time

Start practicing GMAT-like texts

It’s obvious that a reading comp passage won’t be as thrilling as your favorite Dan Brown novel, but the GMAT actually makes RC passages boring on purpose. The test-makers go out of their way to make the text complex, and they like to use natural science and social science topics with which potential business-school students may not be familiar. To prepare yourself, start reading real-world texts that mimic GMAT passage structures. The Economist, Scientific American, and The Wall Street Journal are good places to start, and magazines like Time and Newsweek feature editorial articles that can help you learn...

### How to handle nerves on GMAT test day?

**Categories**: GMAT Exam Day Tips

Test day is no different than any other GMAT prep days. You have to be focused, prepared and give your best shot. But we are not robots, we are humans. So it is natural to feel a little bit anxious. But if you feel: cold sweats, night terrors, the shakes, and so on, then you are showing signs of acute anxiety. Knowing what to expect in the testing center will help you relieve some of the unnecessary anxiety. Here is Knewton's minute by minute breakdown of what to expect in the test center.

1. Arrive early, but don’t plan on studying at the testing center. 30 minutes before liftoff

Show up to the test center 30 minutes before the official time, as the GMAC suggests. Although this may mean waking up even earlier than expected, avoiding any feeling of being rushed is priceless. However, many testing centers don’t allow studying in the waiting room, so don’t plan on getting there early and reviewing notes. Use the time before the test to relax and focus on the task at hand.

2. Locker Room. 10 minutes before liftoff

After presenting your identification and test reservation, you may be given...

### Area , Perimeter and Circumference

A sizeable number of GMAT math test questions belong to the Geometry section. Some of these questions test a candidate’s ability to understand 2-Dimensional Geometry by asking the candidate to calculate the area, perimeter or circumference of a geometrical shape.

The following geometrical shapes are most common – Triangles, Quadrilaterals, Rectangles, Rhombuses, Squares, Circles and Trapeziums.

Triangles – A triangle represents an enclosed shape made by joining three straight lines. The area of a triangle can be calculated as follows:

Area = ½*Base Side*Height of the triangle

In this formula, the Base Side can be any side of the triangle. However, depending on the base side chosen, height of the triangle needs to be ascertained. Height of the triangle is the shortest perpendicular distance from the Base side to the height of the Apex of that triangle. Note that the height of a triangle may need to be calculated outside the triangle, depending on the base side chosen.
