<p>My mother always say that “Repetition is the Mother of Learning.” If money is not an issue, then hearing the information once will be helpful even if he gets rusty on it and needs a little more review later. If you have time this coming summer and he is receptive to these types of classes, then go for it. Like everyone else says, without knowing your son’s specific goals it is difficult to make recommendations. I think that any class would be helpful. The Princeton Review prep books certainly seem to be highly recommended.<br>
Because the classes are so expensive they are really not an option for me, so I am self-studying for the ACT which I am planning to take in April. It would definitely help me to stay on “schedule” with my preparation sometimes if I were enrolled in a class and had someone to hold me accountable.<br>
Best of luck to you and your son!</p>
