Helpful Hints for GMAT Sentence Correction Questions
Part of the GMAT For Dummies Cheat Sheet
The sentence correction questions on the GMAT test your ability to edit written material. Apply the basic rules of English and focus on these guidelines to master the sentence correction questions:
Read the sentence and check the pronouns and verbs in the underlined part for agreement. If the verbs and pronouns check out, look for problems with parallelism or word choice.
If no obvious errors stand out, the answer is probably the first choice, but skim through the answer choices just to make sure you didn't miss anything.
If you spot an error, eliminate answer choices that don't correct the error. Then eliminate answer choices that correct the error but make a new one.
Reread your answer choice within the sentence to make sure it makes sense before you commit to it.
