Eva Holz with SAT Confidential demonstrates how to use the right words in the SAT comprehension section. Don't confuse similar words like affect which is a verb and effect which is a noun. The words imminent and eminent may also be tested. Note also the words inferred and implied which also get confused with each other. Also, don't use the wrong idiom. A wrong idiom may often be paired with a preposition. Finally, don't use the wrong verb. Similar words, idioms and verbs are tested most often in the identifying errors portion of the SAT test.
