When to take SAT 3rd time

Test Preparation
1

<p>My son has taken the SAT twice now. His super scores are CR 680, Math 770, WR 690. He is trying to decide if he should take the SAT again in May or wait until Fall of his senior year. If he takes them in May, he has 3 AP tests he'lll be prepping for and 2 SAT II's he'll be prepping for in June. If he waits until Fall, he can prep more over the summer, but he will also be working and was hoping to be focusing solely on college and scholarship applications. Any thoughts or suggestions?</p>
