Students have to spend extra time preparing for the test. The types of questions are different from what students normally face in class. Exams in high school are focused on a specific topic in a given subject, while the SAT test general topics in math and English. Students in school are tested objectively on the course work while the SAT tests are subjectively on topics that they are suppose to be familiar with. According to the test, all eleventh graders are supposed to know high-level vocabulary and interpret reading passages be very subjective at times.
People interpret reading material differently.
Rich people tend to hire an SAT tutor or enroll in class. These lessons are helping students raise their scores significantly. They get a lower score or get lucky and obtain a good score. Colleges cannot tell who has been tutored and who has not gone to SAT prep classes, giving students, who enroll in class, an immense advantage over students who did not enroll in class. While students are trying to improve their scores, ETS comes up with a few rights and responsibilities for them to follow.
