Sentence Correction questions can include up to 54 words, making for incredibly long sentences and time consuming reading. But similar to GMAT SC - Spot Decision Points, knowing what is likely to be a testable section of a sentence and what is not, you can break apart the sentence into the parts that matter to you as a test-taker. Proper nouns, correctly-applied modifiers, adjectives and adverbs can all be streamlined to make for shorter sentences.

For example, in the sentence:

Originally called BackRub, Google was founded by two Stanford PhD students, Larry Page, whose father, Dr. Carl Victor Page, was a computer science professor at Michigan State University, and Sergey Brin.

The proper nouns and excessive adjectives can be eliminated or condensed, bringing you down to:

Originally called BackRub, Google was founded by two students, Larry, whose father, Carl, was a...

### GMAT Sentence Correction Strategies - Focus on Testable sections

### 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...

### GMAT Solid Geometry - Rectangular Solids and Cylinders

Rectangular Solid

Learn the concepts behind volume and surface area before you start solving GMAT Solid geometry problems. All solid geometry problems come down to this - length, breadth and height. For data sufficiency questions, look out for values of l, b and h. if any of them are missing then it would be easy to eliminate answer choices.

6 rectangular faces constitute a rectangular solid

The formulas you need to remember for a rectangular solid are

Volume = Length (l) x Width (w) x Height (h)

Surface Area = (2 x Length x Width) + (2 x Length x Height) + (2 x Width x Height)

"If length = width = height, that means that the rectangular solid is, in fact, a cube."

### 3 Crucial GMAT Sentence Correction Strategies

**Categories**: Sentence Correction

Of all the question types on the GMAT, a global exam for which the pool of test takers includes more than half of its examinees from outside the United States, Sentence Correction may seem the most arbitrary to prospective examinees. Math we get: nearly all MBA graduates will have to make decisions using numbers and nearly all MBA programs require coursework in areas like finance and accounting for which some baseline math skills are important. But English grammar? Why would schools like INSEAD and ESADE, located in countries where English is not an official language and attracting students from all corners of the globe, be concerned with English grammar subtleties? Especially when, as about 1/3 of the verbal section, sentence correction counts for about 17% of someone’s GMAT score. It’s probably nice to know that everyone can speak the same language, but 17% of someone’s entry value? Isn’t that overkill?

That should be a clue to you that Sentence...

### GMAT Formal Logic Basics: And, or, neither, nor…

We’ve covered, in an earlier blog post, how to deal with the simplest formal logic statement: If X, then Y. But what happens when our necessary or sufficient factors become more complicated? Let’s look at a couple of examples, using the idea of a vegetable salad. The simplest statement and its contrapositive might look like this:

If the salad has lettuce, then it has tomatoes.

If the salad has no tomatoes, then it has no lettuce.

Now let’s add more vegetables (and more complicated logic):

If the salad has lettuce or spinach, then it has tomatoes and peppers.

Here’s an important idea: when you are forming a contrapositive, you already know that the necessary and sufficient factors are switched around and negated. But now you also have to remember that “and” becomes “or,” and vice versa. So the statement above becomes:

If the salad has no tomatoes or no peppers, then it has no lettuce and no spinach.

I find it extremely helpful to individually negate each element of the statement; otherwise, it’s easy to get confused. ...

### Proportions

**Categories**: Ratio and Proportion

A proportion is represented by two ratios which are equated to each other. In GMAT Quant questions, we would be presented with one variable and three values for proportions. Reduce the ratio in either side to the lowest possible value before cross-multiplying.

For example , a proportion can be presented as a/b = c/d or a:b = c:d

So as per our strategy reduce a/b to the smallest possible fraction

ex: 24/10 should be translated to 12/5

GMAT Proportion: A football field is 9600 square yards. If 1200 pounds of fertilizer are spread evenly across the entire field, how many pounds of fertilizer were spread over an area of the field totaling 3600 square yards?

A. 450

B. 600

C. 750

D. 2400

E. 3200

The key word here is “spread evenly”. This implies that the relationship of fertilizer per square foot is uniform, and you can set equal the relationship of the wholes to the relationship of the parts.

A/F = 9600/1200 = 3600/x

Clearly, we can eliminate the zeros on the left side:

9600/1200 = 3600/x

96/12 = 3600/x

Then we can divide 96/12:

8 = 3600/x

Here, we can still reduce left-to-right, by canceling 4 in both:

2 = 900/x

Oh wait! There’s more! Both 2 and 900 are divisible by 2!

### Top 5 Tips to Improve your GMAT Critical Reasoning Score

**Categories**: Critical Reasoning

GMAT Critical Reasoning Questions comprises nearly 1/3rd of all the Questions in the GMAT Verbal Section. It is important that you learn to analyze and identify various parts of the arguments. Follow these 5 Tricks and you will improve your GMAT CR Score:

1. Understand GMAT Critical Reasoning Definitions

Know the definition for terms like assumption, inference, evidence, conclusion, logical flaw, paradox, etc., like the back of your hand. As you go through practice tests, write down any words in the argument, question stem, or answer choice that confuse you – and then look them up! When you have the essential definitions down, you can jump into arguments much more quickly — and you won’t waste any time second-guessing what a question is asking you to find.

2. Identify parts of CR Passages

If you’re having a hard time sorting out the meaning of a passage, take a moment to identify its conclusion and the evidence (statements of fact) and assumptions (unstated ideas) it uses to make that conclusion (the conclusion will often be signaled by words like “as a...

### 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...

### How GMAT Scoring Algorithm Works?

**Categories**: GMAT Score

The GMAT is a computer-adaptive test where your score is calculated by an algorithm that provides you with harder questions (and higher score returns) when you answer previous questions correctly, and with easier questions (and lower returns) when you’ve answered previous questions incorrectly.

Through this method, the GMAT can determine your ability level in a relatively short period – **37 math and 41 verbal questions** – and provide you with an immediate score upon completion of the test. To save you the stress of trying to figure out the secrets of the algorithm, here are some important things you should know about GMAT scoring:

1) Good news: You can get a lot of questions wrong and still do well!

The job of the GMAT scoring algorithm is to determine your ability level by asking you questions that begin to close in on it. Think of how you’d play a game of 20 Questions as you attempt to zero in on the historical figure that your “opponent” has selected:

Was this person famous in the era BC? (No – too early)

Was this person famous before the Middle Ages? (No – still too early)

Was this person famous before the...

### How to study for the GMAT in Two Weeks?

**Categories**: GMAT Study Plan

Knewton: Let us start by saying "Try not to prepare for your GMAT in 2 Weeks". Two weeks is not enough time to master the topics or the test taking strategies (Read GMAT One Month Study Plan and GMAT Three Month Study Plan) But circumstances like a B-School Deadline might force you to cram for the test in two weeks. Follow this efficient GMAT Study Plan:

Day 1 – Diagnosis: Take a practice test. This will likely be your one and only assessment. If you score evenly on both sections, then you will need a more comprehensive study plan. If you ace verbal but bomb the quant, then you know to focus your attention there.

Days 2 to 4 – Prime the Pump: After you take an official practice test, spend the next few days going through as many practice problems as possible. If you have an Official Guide, make certain you read the explanations for all of the questions you answer incorrectly. Try to focus...

### GMAT Data Sufficiency Strategy - The Obvious Answer Trap

**Categories**: Data Sufficiency

Data Sufficiency questions are supposed to be hard; more so than any other question type they tend to represent a chess match between you and the author, as the author has two chances to get you to make a mistake. She won’t likely waste either statement giving you an easy pass – the questions have to elicit something from you in terms of efficiency or ingenuity in order to answer them correctly, so if an answer choice seems obvious within 15-20 seconds and you can’t spot a trap, well, you just fell into the trap. Consider the question:

What is the value of x?

1) 3x + 2y = 15

2) y = (-3/2) (x – 5)

This should pretty obviously be C.

Two equations, two variables, neither works alone but both work together, right?

But that is too easy, and the GMAT won’t often give you the answer that quickly. Much as though the author had moved a pawn...

### Three Types of GMAT Profit and Loss Problems

You will encounter the following three types of Profit/Loss problems in the GMAT:

Profit/loss as percentage of Cost Price

In this case you will be given the cost price and sales price, and will be asked to simply calculate the profit/loss incurred by the seller by entering into the given transaction. This will be done by dividing the difference between the Sales Price and the Cost Price by the Cost Price. To convert the decimal into a percentage, you will multiply it by 100.

Profit Percentage = ((Sales Price - Cost Price)/Cost Price) x 100

Selling price = Z x (Cost price)

Where Z is any positive number. When Z < 1 we have a loss. When Z = 1 we have neither profit nor loss. When Z > 1 we have a profit.

Profit or Loss % = (Z - 1) x 100.

Selling price = [(Y / 100) + 1]x (Cost price)

Where Y is the profit or loss percentage. When Y < 0 we have a loss. When Y = 0 we have neither profit nor loss. When Y > 0 we have a profit.

Profit/loss as percentage of Sales Price

Sometimes the problem will be worded differently and will require the test taker to calculate...

### Top 10 Ways to Save Time in GMAT

1. Prepare: This one is on the obvious side, but too important to leave off the list. The most important things you can do to prepare for the GMAT is to understand all the concepts tested and to be familiar with all the question types. There is no magic formula–the best strategy is to spend a lot of time beforehand practicing and familiarizing yourself with the various concepts and question formats.

2. Be confident: If you know the right answer, stick with it. Often on, say, a Problem Solving question, you’ll need to figure out the right answer before you even get to the choices. Don’t waste time second guessing yourself when you see a different answer that looks appealing; you studied for this, you did the question properly. Select your answer and proceed to the next question.

3. Don’t spend time on calculation: This one is obvious but often overlooked. Data Sufficiency problems ask you to say when you have enough information to answer the question in the prompt, not to actually compute the answer. Sometimes you need to work all the way to a solution, but often, all you need to know is how to get the...

### Idioms

On the GMAT sentence corrections, an “idiom” is a recognized grammatical construction that is a rule simply because of tradition. The idiom constitutes the ultimate tautology: we say something a certain way because, well, that’s how we say it.

On the test, most of the idioms you will face involve preposition usage. Why do I listen “to” the radio instead of listen “at” the radio? We say “listen to” because that is how English speakers have said it for hundreds of years. We like it that way, and we are not willing to change.

For some test-takers, idiom errors can be the easiest to spot on the exam. To these test-takers, an idiom error sticks out like a sore thumb. When they read something like “listen at the radio,” they hear dissonance. The only way to restore grammatical harmony is to replace the grating “at” with the soothing “to.” Balance is restored.

English as second language

Not everybody thinks this way. For many who learned English as a second language, and even for those who have a purely logical--as opposed to intuitive--understanding of language, idiom errors are extremely difficult to detect. After all, there is no logical explanation for why we say “listen to” instead of “listen at.”...

### How to solve work and rates problem in GMAT

Carefully go through the following question types. These are the standard work rate problems that you would encounter in your GMAT Exam.

Working Together

In questions where individuals work at different speeds, we typically need to add their separate rates together. Make sure you keep your units straight. This doesn’t mean wasting time and writing each and every one out, but rather simply recognizing their existence. Note that when working together, the total time to complete the same task will be less than BOTH of the individual rates, but not necessarily in proportion. Nor, are you averaging or adding the given times taken. You must add rates.

Q) A worker can load 1 full truck in 6 hours. A second worker can load the same truck in 7 hours. If both workers load one truck simultaneously while maintaining their constant rates, approximately how long, in hours, will it take them to fill 1 truck?

A. 0.15

B. 0.31

C. 2.47

D. 3.23

E. 3.25

The rate of worker #1 is 1 truck/6 hours. This can also be 1/6 trucks/1 hour. The rate of worker #2 is 1/7. When together, they will complete 1/6 + 1/...
