Sentence correction:
1) Subject verb agreement
Singular subject – Singular verb; Plural subject – plural verb.

Tenses :
1) Represents the time of Action As in Past, Present and the future.

2) Types of tenses:
i) Simple present tense:
Used to discuss permanent situation and frequency of events
Eg. I like to read books.
The Earth is round.
The bus leaves at 10 am daily.
j) Simple past tense:
Discuss actions that happened at a specific time in the Past
Eg. I saw a play yesterday
She washed her car
k) Simple future tense:
Has to diff forms “will” and “be going to” . . .
“Will” expresses a voluntary action or a promise
Eg. I will do that.
I will give you call.
“be going to” expresses a plan
I am going to spend most of my salary this month.
Who are you going to invite for the dinner.
l) Present Continuous tense:
m) Past Continuous tense:
n) future Continuous tense:
o) Present perfect tense:
Discuss actions that happened at an unspecified time in the Past
Has/have + Past participle
Eg. You have seen that play so many times.
You have changed so much since the last time I saw u.
p) Past perfect tense:
Refers to those cases in which two actions are taking place in the past in the same sentence one before the other.
Had + Past participle
Eg. She called when he watched the tape.
She understood the movie because she had read the book.
q) Future perfect tense:
r) Present perfect continuous tense:

Has/have + been + present participle

Had + been + present participle
Eg. They had been walking for 1 hr until she arrived.
I had been working for the company for two years.
t) Future perfect continuous tense:
3) The use of “has had” and “had had”
Generally the above is used when the verb itself is in the form of has or had
“Has had” is used when the sentence is in the form of present perfect tense(i.e it talks about a action that took place in an unspecified time in the past)
E.g John has had many cars till now.
“Had had” is used when the sentence is in the form of past perfect tense(i.e it talks about two actions that took place in the past one happening before the other one)
E.g John had had many cars before he thought of moving out of the league and buying Ferrari.

1) Replaces a noun. It should clearly specify which noun the pronoun modifies.
2) It should agree in number to the noun it replaces.
3) Avoid pronouns in the state of confusion regarding which noun it is modifying.
Eg. The residents association informed the municipality that it is getting the park cleaned.
Here “it” may refer to both residents association and municipality, so avoid the pronoun “it”.
4) How are pronouns generally tested.
a) The pronoun refers to more than one noun as discussed in the point no 3.
b) There may be no antecedent of the pronoun
Eg Despite the board of governors supporting the measure, they keep voting against it.
They is not having any noun as antecedent, hence avoid pronoun usage. The correct form should be. .
Despite the board of governors supporting the measure, the shareholders keep voting against it.
c) The indefinite antecedent.
Incorrect : These days they have started charging you for cabin baggage in the airlines.
They is ambiguously used in the above sentence, though it seems to be correct.
Correct: Cabin baggage is charged for by many of the airlines these days.
d) Use of that and which
“Which” is used only to modify the subject.
Eg. The fifth car, which is black in colour, belongs to Jack.
Here the sentence is talking exclusively of a car that is fifth in number and also is black in colour.
Two rules for use of which,
1) It should come immediately after the comma.
2) It must refer to a noun that comes just before the comma.
“That” is used to clarify the subject, hence is very important.
Eg. The fifth car that is black in colour belongs to Jack.
Here the sentence is talking about a car that is fifth black one. But in series it may be anywhere in position (10th/13th/19th . . .).

On the GMAT ‘which’ is only explanatory and is not needed to identify the subject of the sentence; in fact you can easily remove the phrase starting with ‘which’ and yet the meaning of the sentence would remain unchanged whereas ‘that’ is necessary to identify the subject of the sentence and cannot be done away with.
e) Use of “Who” and “Whom”.
The difference between who and whom is exactly the same as the difference between I and me, he and him, she and her, etc.
Who is an object(the object performs the action of a sentence)
Whom is a subject to/about/on the action is performed.
1) The modifier should be placed as close as possible to what it modifies.
2) Misplaced modifiers
a) Participle phrase
A phrase that starts with a present or a past participle (may or may not be preceded by a preposition). Whenever a sentence starts with a participial phrase there will almost always be a misplaced modifier lurking around the corner.
Incorrect: Educated at Eton and then at Oxford, it was surprising that George could not get into a decent business school.
Correct: Educated at Eton and then at Oxford, George surprisingly could not get into a decent business school.
Incorrect: Coming out of the house, John’s laptop was stolen.
Correct: Coming out of the house, John was robbed of his laptop.
b) Use of adjectives and adjectival phrases
Incorrect: Tall and handsome, a striking figure was cut by John.
Correct: Tall and handsome, John cut a striking figure.
3) Dangling modifiers
The modifiers which seem to modify the right part of sentence but grammatically it doesn’t
Eg. Using a stethoscope, heartbeats can be detected.
The modifier “Using the stethoscope” is called a dangling modifier. It is not heartbeats that used the stethoscope but the person who is using it. So something has to be introduced in the above sentence.
Using a stethoscope, a doctor can detect heartbeats
1) Compared item must be logically similar:
The students in my class are smarter than the other classes
Comparison is done between students and classes, hence incorrect.
The students in my class are smarter than those in other classes.
2) Compared items must be grammatically similar:
Compare nouns with nouns, verbs with verbs, phrase with phrase, clause with clause and so on . . . . . .
3) The way comparison is tested in GMAT:
a) Unclear comparison
Incorrect: John loves Tina more than Katy.
This sentence can be interpreted in two ways – either John loves Tina more than he loves Katy or John loves Tina more than Katy loves Tina. The problem can be corrected by adding some more words to the sentence.
Correct: John loves Tina more than he does Katy.
Correct: John loves Tina more than Katy does.
Point to remember that the above two sentences convey different meanings although both of them are grammatically correct.
b) Illogical comparison:
Same as point no.2 mentioned above.
c) Comparative and Superlative forms:
When comparing more than two things use the superlative form
Incorrect: Among all my students, John is more intelligent.
Correct: Among all my students, John is most intelligent.

The Miscellaneous errors:
1) The subjunctive mood
There are three basic mood in English grammar : Indicative mood, imperative mood and Subjunctive mood.
2) The subjunctive mood is used in the following two situations
Situation 1: To indicate a hypothetical situation, a wish, or a circumstance contrary-to-fact.
When contemplating hypothetical or contrary-to-fact situations, always use ‘were’ and ‘would’. Please note that even if the subject is singular you will still use ‘were’ and not ‘was’. If I were rich I would buy a BMW.
If petrol were cheaper I would use my car everyday.

Situation 2: To make a suggestion, demand, desire, etc.
Verbs like order, suggest, demand, etc. must be followed by ‘that’ and the infinitive form of the verb being ordered or suggested, without the ‘to’.
The teacher recommended that Jerry be expelled from the class.
The manager demanded that John show up for work on time.
3) How to figure out that when the question is testing us on subjunctive mood?
1. Check for words such as ‘if’, ‘wish’, etc. Though these can also be used in the other moods, they are most commonly tested on the subjunctive mood.
2. Ask yourself if the sentence is talking about an uncertainty, a wish, a suggestion, a demand, etc. If it is then you are dealing with the subjunctive mood.
4) When and where:
On the GMAT ‘where’ will always refer to a specific location and ‘when’ will always refer to a specific time period; else their use is wrong.
Correct: The town where I was born is known for its fishermen.
Correct: It was a historic event when, in 1947, India achieved independence.
Incorrect: When the price goes up the demand falls down.
Incorrect: The Company where I work has gone bankrupt.
4) Each other and one another:
‘Each other’ is used for two things; ‘one another’ for more than two.
The two men are pointing out each other’s mistakes.
The students are pointing out one another’s mistakes.
5) Whether or if
‘If’ is used to introduce a conditional idea or an idea that has just one possibility whereas ‘Whether’ is used to introduce alternative possibilities, usually with ‘or not’ implied or explicitly stated in the sentence.
If you study hard you will surely do well on the GMAT.(Conditional case)
I can’t decide whether to study or to go out with my friends.(Alternative case)
Both if and whether can be used in a single sentence as well
You need to decide whether you will be able to control your temper if he asks you to get out of his office.
6) Everyday vs Every day:
‘Everyday’ is an adjective meaning ‘ordinary’ or ‘commonplace’. An adjective, in case you’ve forgotten, is a word that modifies a noun. Eg. ‘everyday occurrence’, ‘everyday people’, etc.
‘Every day’ is an adverbial phrase that tells us how often something takes place. An adverb is a word or phrase that modifies a verb (most of the time).
7) Like and Such as:
On the GMAT ‘like’ means ‘similar to’ and ‘such as’ means ‘for example’
Important: Even if ‘such’ and ‘as’ are separated in a sentence, the sentence is still correct.
I want to eat some such sweet as a chocolate or a pastry.
8) Compare to v/s Compare with:
‘Compare to’ is used to point out the similarity between two unrelated things. More than a comparison, it’s actually just a statement stating that one thing is similar to another to emphasize that particular thing.
John compared his wife’s face to the moon.
‘Compare with’ is used to actually compare two things by pointing out the similarities as well as differences between them.
Jerry is comparing a Toyota with a Honda.
9) Due to v/s Because of:
Due to is used to replace “caused by”
10) Agree to v/s Agree with
You agree ‘with’ a noun and you agree ‘to’ a verb.
John agreed to run an extra mile. (‘run’ is a verb so agree ‘to’)
John agrees with his brother. (‘brother’ is a noun so agree ‘with’)
11) Shall v/s will
Use ‘shall’ when speaking in the first person and ‘will’ when speaking in the second or third person.
I shall win the championship BUT You/We will win the championship.
12) Will v/s would
Use will to refer to some event that will happen in the future in relation to the present and use would to refer to the future in the past.
13) Farther v/s Further
‘Farther’ refers to actual measurable distance whereas ‘Further’ refers to degree, quantity, time, or some such other quality that cannot or is not being precisely measured.
14) Differ with v/s Differ from
Use ‘differ from’ to imply ‘unlike’ (as in one thing differing from the other) and ‘differ with’ to imply ‘disagreement’ (as in differing with a point of view).
15) Rather than v/s Instead of
‘Rather than’ is used to express preference of one thing over another whereas ‘instead of’ is used to replace one thing with another.
‘rather than’ is a conjunction so it can be followed by anything – noun, phrase, clause – whereas ‘instead of’ is a preposition so it can be followed only by nouns.
