Study Hall is an SAT preparatory service. Henry, the man who runs it, is a very nice person who works with you one on one, problem by problem, to get better at taking the SAT test. I went there almost every day for two months and my score dramatically improved. My friend also went to Study Hall and ended up getting a perfect score. Even if your child is smart, this man knows how the test works and how to beat it. He is really very very friendly. You pay $500 and then you can take a test whenever you want at no additional charge. Plus, you can have free cokes at every visit! The best in SAT prep.
