SAT Prep

Today, I read an article in our local newspaper about SAT prep courses. Apparently, people in relatively well-off suburbs don't even question the necessity of these courses and spend willingly thousands of $ for SAT prep and college coaches.

I'm wondering whether there are any research studies that prove these classes actually make a huge difference. To me, it seems to be just a big business. My son will take the SAT in spring and I really hope, he will do okay without us spending big money. In two weeks, he will take a free practice test at his high school. Then we will know more.
