Today, the official preparation materials for the SAT are provided for free to anyone with internet access through Khan Academy, and others in this thread have claimed they are as good as privately available tutoring. I suspect that no matter how effective the publicaly available test prep is, somebody will always be able to convince parents to pay them to do better, whether or not that actually works. For strong cultural reasons, having the police enforce a ban on all nonfree activities intended to prepare students for the test is not viable.
