Sentence correction section in GMAT is the most complex part of the verbal section. Most of the standardized tests include the sentence correction part, but the most difficult one is in the GMAT. Needing to know what the GMAT would target and learn accordingly would go a long way. There is a list of five top ticks that would help one to master the most difficult and toughest grammar situations. The rule number one is all verbal are not verbs. The most important thing to recognize in a GMAT exam is the ‘ing’ form of a word, which without a helper verb like ‘is’, ‘was’ or ‘am’ does not behave like a verb. Without the helper verbs, the verbal acts as a noun or modifier. If the particular subject corresponds to a verbal and not a verb, then the sentence is considered to be a frment.
Rule number two is that if in a sentence grammar is correct, a verb is in the same clause as its subject. If a sentence does not contain the subject and its concern verb in the same clause, then it is called a frment. ‘That,’ ‘which,’ ‘who,’ ‘whose,’ and ‘whom’ are the words that begin new clauses, and a verb in one of these clauses cannot correspond to a subject. The next point is that when clauses are not connected properly, and then there are errors in the sentence. If a clause can stand on its own as a separate sentence, then it is called as independent clause. For this, two independent clauses must be separated by a semi-colon or a comma that pairs itself with a semi-colon. If not, the sentence is called a run-on and is considered incorrect. There are three ways to fix the incorrect sentence, one is by separating the clauses with a semi-colon, next is to separate the clause with the right conjunction, or the last one is to make the clause dependent with the help of a conjunction.
In cases of a describing phrase at the start of the sentence, the description must be the noun followed after the comma. The descriptive phrase does not contain a subject-verb pair and is set off from the rest of the sentence by a comma. Sometimes, these phrases begin with a participle, either the –ing form of the verb, or the –ed version of the verb. The modifying phrase at the start of the sentence must logically announce the first noun that arrives after the comma, otherwise the sentence might contain a misplaced modifier. Conjunctions like ‘because,’ ‘although,’ ‘since’ can begin a sentence or join clauses, but not the main subject not the main verb can be in a clause beginning with one of these words. These are some of the golden rules followed by the GMAT takers every time. This would help the first-timers who are taking up the exam to get a better insight of how the test is going to be and get them prepared for the same.
