26 points are usually gained from taking a high school course
30 points are typically gained from a private course
And a private tutor can help students achieve a 37 point increase compared to no preparation.
Test preparation companies convince students that they only need to know how to take the test to get a good score, and they promise to provide students with the tricks for doing well. Some of these expensive test preparation services, like the Princeton Review and Kaplan, guarantee a score increase even though the College Board claims test preparation is unsuccessful or useless.
Family income is directly related to the likelihood of a student using private courses or tutors, the two most expensive preparation tools, instead of no preparation.
Why is This Happening?
- Families with higher incomes usually live in neighborhoods where the public school systems are higher quality
- Families with high incomes often send their children to private schools where they get a superior education
- Families that earn at higher levels can afford more books, high-speed internet access, and other educational tools that enhance their children's education
- Students from high-income families are more likely to have a stay at home parent who can help with homework or other aspects of their child's education
