Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
A commonly tested GMAT concept is that of "each of/one of + plural noun". The verb that immediately follows will agree with the subject "each of/one of" if there is no relative pronoun following.
Eachof the booksreminds me of her
In red is the independent clause and in blue is the prepositional phrase. "reminds" in this case is part of the independent clause and should be conjugated with the subject of the independent clause "each". In blue is just extraneous information splitting the independent clause. Do not get bothered by it. "reminds" should still be singularly conjugated.
Eachof the booksthat rest on the tablereminds me of her
In the above sentence, the independent clause and prepositional phrase have the same explanation as in the first example. However, there is an intruder, another obstacle splitting the independent clause; the relative/restrictive clause in green. A relative clause usually refers to the closest noun and in this case, it is "books" from the prepositional phrase. Hence, it is why "rest", the immediately following verb, will be conjugated with "books" rather than "each". _________________
As a stand-alone word and as a collective noun, "number" can take a singular or a plural form.
eg Two hundreds persons were at the party; the number(s) is just astounding. --> either form can be used
However, when preceded by an article and followed by preposition "of", "number" is singular and the verb that follows "number" will be conjugated singular or plural depending on whether there is a definite or indefinite article in front.
eg The number of calls is overwhelming --> definite article so verb is singular
eg A number of people are responding --> indefinite article so verb is plural _________________
According to TPR, The Princeton Review, the most common errors to look for when you read a sentence correction question are:
1. Pronoun Errors: If a sentence contains a pronoun, check to see whether it clearly refers to the noun it is replacing; also check to see whether the pronoun agrees in numer with the noun to which it refers.
2. Misplaced Modifiers: If the sentence begins with a modifying phrase, check to make sure that the noun it modifies comes directly after the modifying phrase.
3. Parallel Construction: If a sentence contains a list of things, or actions, or is broken up into two halves, check to make sure the parts of the sentence are parallel.
4. Tense: If the answer choices contains different verb tenses, make sure that the tense of the verb or verbs in the original sentence is correct. For the most parts, verb tense should be consistent throughout a sentence.
5. Sentence-Verb Agreement Errors: ETS sometimes put extraneous prepositional phrases between the subject and the verb. Cover up these phrases so that you can see whether the subject and the verb of each clause in the sentence agree with each other.
6. Idiom: If a sentence contains an idiomatic expression that seems wrong to you, try taking the expression out of the sentence and creating a sentence of your own with the suspect expression.
7. Apples-and-Oranges: When a sentence makes a comparison, check to see whether the two things compared are really comparable.
8. Quantity words: Whenever you see a quantity word (countable vs. uncountable; two vs. three or more) check to see if it used correctly.
You can expand your list to include as many types of errors as you like. Obviously the more types of errors you can identify, the better prepared you'll be to take the test. But you should bear in mind that while there are other types of errors, these errors don't come very often on the GMAT. Some of the other errors to consider: redundant words, misuse of the subjuntive mood, and the use of the passive voice when the active voice is possible.
1) Answer choices in which the word "being" is a verb are rarely correct. Pay special attention to where and how "being" is used at the end of the answer choices. This is a Kaplan takeaway strategy
2) "There" constructions are rarely correct. If you see "there" WITH a comma before it, it's probably wrong
3) If you see "which" WITHOUT a comma before it, it's probably wrong.
4) Consider, regard....as, think of......as: there is no as after consider, while both regard and think of need the as.
5) To be/Being: In general, avoid the construction to be/being because they are usually passive. To be/being are commonly used in junk answer choices.
6)“after when” is WRONG
7) From x to Y - CORRECT, From x up to Y - INCORRECT
8) Rates for - CORRECT, Rates of – INCORRECT
9) If “who” is present it should refer to one before the comma.
10) “so much.....as” is preferred if it is preceded by a negative. Ex: She left not so much as a trace.
11) Have + verb (-ed) + present participle (-ing) is WRONG ex: “have elected retiring” should be “have elected to retire”
12) A relative pronoun (which, that or who) refers to the word preceding it. If the meaning is unclear, the pronoun is in the wrong position. The word "which" introduces non-essential clauses and "that" introduces essential clauses. "Who" refers to individuals; "that" refers to a group of persons, class, type, or species.
Wrong: The line at the bank was very slow, which made me late.
Right: I was late because of the line at the bank OR The line at the bank made me late.
13) “Less” and “amount” refer to non-countable things and answer: “How much?” [soup].
14) "Fewer" and "number" refer to countable things and
answer: "How many?" [people].
15) "if" vs. "whether" vs "whether or not". if these are being tested in one sentence choose "whether" almost 100% of the time!!!
16) Disinterested vs Uninterested
Disinterested: neutral, unbiased
Ex: The best judges are disinterested.
Uninterested: bored, not interested
Ex: Uninterested in his homework, Martin nodded off.
17) Who vs Whom
If you can’t get who and whom straight, try this trick: rephrase the sentence to get rid of who or whom.
If you find you’ve replaced who/whom with he, she, or they, then "who" is correct.
If you find you’ve replaced who/whom with him, her, or them, then "whom" is correct.
The conditional might trip you up or give you pause, but it’s actually a wonderfully simple verb form to get right.
The formula always goes: If.....were.....would. That’s it! There’s nothing else to memorize.
Ex: If I were principal, I would let everyone leave at eleven a.m.
Note that it’s never correct to say if . . . was . . . were.
The title of the song “If I Were a Rich Man” is an excellent way to remember the use of were with the conditional.
Like vs As
'Like' is used to compare people or things (nouns)
Ex: Jack and Jull, like Humpty Dumpty, are extremely stupid.
'As' is used to compare clauses. A clause is any phrase that includes a verb
Ex: Just as jogging is a good exercise, swimming is a great way to burn calories.
Each other vs One another
Each other - used when two persons are involved
Ex: Ross and Rachel love each other.
One another - used when there are more than 2 people
Ex: The three brothers love one another.
As Long As vs So Long As
As long as - deals with physical comparision
Ex: The baseball bat was as long as the club
So long as - deals with a condition
Ex: So long as you maintain your cool, the meeting should be fine.
Equal vs Equivalent
Equal should be used only in its strict sense.
Ex: 4+3 is equal to 5+2
Equivalent is preferable when we are saying that two thing s are not entirely identical, but are almost equal.
Ex: Country X spent $xx on something, equivalent to the GDP of country Y.
For disjunctive phrases with the use of â€˜orâ€™, â€˜either-norâ€™ or â€˜neither-norâ€™, find the subject nearest to the verb and make that verb agree in number with this subject.
Neither Wilfred nor his friends are going to work.
Either his friends or Wilfred is going on a holiday.
Paul or GMAT members are allowed to attach documents to the forum.
When either or neither are in a sentence alone (without or/nor), they are not considered to be part of a disjunctive phrase. In such cases, they are considered singular and take only singular verbs.
Re: Mar 24 11:34 post supra do you mean either-or for this portion
"For disjunctive phrases with the use of â€˜orâ€™, â€˜either-norâ€™ or â€˜neither-norâ€™, find the subject nearest to the verb and make that verb agree in number with this subject."
Either-or, Or, and Neither-nor all are part of disjunctive phrases. Such disjunctive phrases usually have two subjects, and to determine the form of the verb, whether it's plural or singular, depends on the noun nearest to the verb.
I'll give some more examples below:
Or Boys or Girls are allowed to join the club.
The seven dwarves or snow white is going to have a party.
Either... or and Neither... nor Either you or me is going to win the contest.
Neither you nor me is going to win the contest.
Either Jack or his friends are going home.
Neither Jack nor his friends are going home.
Either his friends or Jack is going home.
Neither his friends nor Jack is going home.

percent, number, fraction, some ...
X of Y X: %, percent, number, fraction etc. Y: subject
is a case where the combined subject is singular or plural, based on whether Y is singular or plural.
A high percentage of the population _____is____ voting for the new school.
A high percentage of the people ____were_____ voting for the new school.
are the correct answers as population is a singular and people is a plural subject.
Some more examples: 10% of the studentsare not in the class (plural) One third of the cakehas been eaten (singular)
One more note: The following words can result in either a singular or plural subject based on the subject it acts on
1) Some of : Example: Some of the cookiesare missing - OK Some of the cakeis missing - OK
I'll just touch on the last part of this ealier post. Some, Any, Most, All, None are all indefinite pronouns. To determine if these pronouns are singular or plural dependson the object of the 'of' construction.
Some of the girls (plural girls) are beautiful.
Some of the cake (singular cake)is eaten.
The two examples above applies for the indefinite pronouns I just mentioned.
