<p>Most schools that have early action/decision are accepting scores from the Oct. and even Nov. senior year SAT test dates, so don't worry about that. (Peek at the admissions websites of some schools he may be interested in to see what is the latest test date they can accommodate for EA/ED.) Jan. or Mar. sounds good for a first SAT I, June for SAT IIs (assuming May is AP test time and might be too much for SATs also, although I know kids who do both APs and SATs in May), and then Oct. for an SAT I retest if he feels he can improve.</p>
