Hybrid quant questions on the GMAT contain multiple steps with twists and turns. You must complete each step quickly to finish the problem in under two minutes. Don't underestimate how much time it takes to mull over how the different parts fit together and to transition from one line of thinking to another.
Try the following problem.
A student cuts 80 rectangles from construction paper, all of which are at least 10 inches in length and in width, and 20 percent of the rectangles that are greater than 10 inches long are exactly 10 inches wide. If 40 of the rectangles have a length of exactly 10 inches and 50 of the rectangles are greater than 10 inches wide, how many rectangles have a perimeter of greater than 40 inches? (Note: Assume that width and length are interchangeable; in other words, width does not have to be shorter than length.)

Building a vocabulary is hard. You have to read a lot. We mean a lot. Read. Read. Read. However, when you are faced with standardized tests, like the ACT, SAT, GRE, GMAT, HSPT, ISEE, SSAT, LSAT, etc. you don't have much time to build a great vocabulary, if you already don't have one.
Here is a handy tip to quickly build a great one if you are pressed for time.
Replace the word 'very' with a new word!

A key to Scoring High on the GMAT
One of the most common errors in Sentence Correction on the GMAT is an incorrect, or dangling, modifier. These modifiers are often hard to detect. However, it is crucial to detect them if you want to score high on the GMAT. This blog attempts to eliminate confusion and frustration of students who are familiar with dangling modifiers.
What are Dangling Modifiers, or "Danglers"?
A dangler is a phrase that is used at the start of a sentence to describe something, but that something is not the subject doing the main action of the sentence. Since dangling modifiers don't attach to what comes right after them, they "dangle." The result is that they can be read as describing the subject of the sentence when they actually don't, which can be funny or just confusing. Let's see some examples.
The Usual Suspect
Watch out for an ing word if it's near the front of a sentence. Most likely, it is a dangling modifier. To find it, ask a whodunit question. Who is doing the talking, reading, singing, walking, etc? You may be surprised by what you find. Often, the danglers are participles.
With Present Participles
With Past Participles
With Prepositional Phrases
Often prepositions, a words that show position or direction, can lead your astray.
Pin the Tail on the Donkey
Often adjectives get pinned to the wrong part of a sentence and become danglers.
Hitch your Wagon
A dangling adverb at the front of a sentence is similar to a horse that's hitched to the wrong wagon. Such adverbs are easy to spot because they often end in 'ly'. When you see one, make sure it is hitched to the right verb.
The Infinitive Trouble
Some of the hardest danglers to see begin with to.A sentence that starts with an infinitive (a verb usually preceded by to, like to say, to laugh) cannot be left to dangle. The opening phrase has to be attached to whoever or whatever is performing the action.
Can't find a dangler? It might hiding as a 'like' or as an 'unlike'. Consider this likely example.

The semicolon is one of the most useful but least used punctuation marks.
Many people avoid the semicolon. Some even seem to dislike it, but it does not have to be that way. The source of avoidance or dislike is the lack of understanding of the proper role of the semicolon. If a comma is a yellow light and a period is a red light, the semicolon is a flashing red--one of the lights you drive through a brief pause.
Here's when to use it.
1. Use a semicolon to separate clauses when there's no and in between.
2. Use semicolons to separate items in a series when there's already a comma in one or more of the items.
Think of the colon as punctuation's master of ceremonies. Use it to present something: a statement, a series, a quotation, or instructions. But remember that a colon is an abrupt stop, almost like a period. Use one only if you want your sentence to brake completely. Here is how to do it.
1. Use a colon instead of a comma, if you wish, to introduce a quotation.
Many people prefer to introduce a longer quotation with a colon instead of a comma.
2. Use a colon to introduce a list, if what comes before the colon could be a small sentence in itself (it has both a subject and a verb).
Just don't use the colon to separate a verb from the rest of the sentence. In John's shopping cart were: a Bordeaux, a Merlot, and a Chardonnay. If you don't need a colon, why use one? In John's shopping cart were a Bordeaux, a Merlot, and a Chardonnay.
And that's it folks. Wasn't that easy?

The comma is a small mark, but it is perhaps the most important punctuation in grammar. Despite that, comma confusion is one of the most common grammatical problems that students face. This blog attempts to help students with proper comma usage.
Short Summary (TL;DR)
1. The Pause
Commas, commas, commas. They often are a source of confusion. How do you use without getting lost in grammatical jargon? Thanks to Patricia T. O’Conner's book on grammar, Woe is I: The Grammarphobe’s Guide to Better English in Plain English, commas can easily be understood. We let her tell you about them in her own words:
"When you talk, your voice, with its pauses, stresses, rises and falls, shows how you intend your words to fit together. When you write, punctuation marks are the road signs (stop, go, yield, slow, detour) that guide the reader, and you wouldn’t be understood without them.
"If you don’t believe me, try making sense out of this pile of words:
Who do you think I saw the other day the Dalai Lama said my Aunt Minnie.
"There are at least two possibilities:
"Who do you think I saw the other day?" the Dalai Lama said. "My Aunt Minnie."
"Who do you think I saw the other day? The Dalai Lama!" said my Aunt Minnie."
"Punctuation isn’t some subtle, old-fashioned concept that’s hard to manage and probably won’t make much of a difference one way or another. It’s not subtle, it’s not difficult and it can make all the difference in the world.
2. Separate the Parts of Speech
If you get commas right, you will get most of your punctuation right. How do we use them?
Long and short division
Use a comma to separate big chunks (clauses) of a sentence with and between them.
If there’s no 'and' in between, use a semi-colon instead:
Use commas to separate a series of things or actions.
In a series, you can leave out the comma before "and". It’s just a matter of taste. 'And' can also be thought of as a separator, a break, so a comma often is unnecessary.
3. Comma with Subjects and their Verbs
With few exceptions, a comma should not separate a subject from its verb.
Incorrect: My friend Amanda, is a wonderful dancer.
Writers are often tempted to insert a comma between a subject and verb this way because speakers sometimes pause at that point in a sentence. But in writing, the comma only makes the sentence seem stilted.
Correct: My friend Amanda is a wonderful singer.
Be especially careful with long or complex subjects:
Incorrect: The things that cause me joy, may also cause me pain.
Correct: The things that cause me joy may also cause me pain.
Incorrect: Navigating through snow, sleet, wind, and darkness, is a miserable way to travel.
Correct: Navigating through snow, sleet, wind, and darkness is a miserable way to travel.
4. Comma After Introductions
Introductory clauses are dependent clauses that provide background information or "set the stage" for the main part of the sentence, the independent clause. For example:
Introductory phrases also set the stage for the main action of the sentence, but they are not complete clauses. Phrases don't have both a subject and a verb that are separate from the subject and verb in the main clause of the sentence. Common introductory phrases include prepositional phrases, appositive phrases, participial phrases, infinitive phrases, and absolute phrases.
Introductory words (SHFM)
Introductory words like however, still, furthermore, and meanwhile create continuity from one sentence to the next.
