Anyone have any experience with the ACT/SAT prep services? We were referred to one by a friend and the service does one on one tuturing based on the student's performance on a proctored practice exam. They draw up a study plan to address the student's weaknesses. They claim their services raise test performance, on average, 4 points. Just curious if anyone has any first hand feedback positive or negative. They had a lot of convincing things to say, but I am in sales and I couldn't help thinking the whole time that this is a business and they want to sell as much of their product as possible.
