Most Imp Tip : Always read the entire sentence, never try to ignore the full sentence based on some standrad error in first part of sentence. Sometimes intended meaning of sentence is different from what we are expecting.

Elimination process works very well in sentence correction

Give attention to subject verb agreement, Pronoun Subject agreement and verb tenses

Standrad prepositions such as difference between among vs between, not only but also, either or, neither nor

Parallelism of sentences. Here one compare two or more phrases and all of the phrases should be of similar form

Elliptical verb phrases

Use of which, where, that and semicolon

Appropriate use of “this”, Is it refering to subject or phrase clearly

Fewer vs less, Who vs Whom

Run on sentences ( prefer the short and concise sentences only)

Proper use of adverbs

Note the intended meaning of the original sentences and eliminate any answer choice that distorts the meaning of original sentence

Never read the choice A as it is a repetition of underlined part of original sentence.

Ignore punctuation, It is never tested
