Types of Questions in GMAT Sentence Correction

There are a few common errors that are tested in the GMAT sentence correction part. Being able to recognise the error type in the questions can help you in getting a better score in the exam since you will be aware of how you need to approach the question. Let’s take a look at some of the common errors:

Subject-Verb Agreement

These questions will test your knowledge in identifying the subject and the verb in a sentence, and ensuring that they match with each other. For example, if the subject is in singular form, the verb also needs to be in singular and if the subject is in plural, the verb will similarly be in plural form. These questions are often made trickier by placing many words between the subject and the verb to confuse the candidate.

Pronoun-Antecedent Agreement

These types of questions require you to identify whether the pronoun and its antecedent is in the agreement or not. The antecedent is the word that the pronoun replaces, and therefore if there is no clear antecedent present in the sentence, that itself will count as an error. Additionally, you need to ensure that the pronoun and antecedent matches in form.
