<p>I would say - no. if he is happy with his SAT score and it is on the high end of where he is applying then definitely why bother when he has enough on his plate coming up. My S took his SAT in June as a rising senior (the day after he finished his junior year) and that was it. Done. It was his first time, only time to take it that counted (took SAT as a 7th grader for Duke Tip). It was such a relief to be done with the testing and focus on the college applications. However, my D might take the ACT and see which one she is stronger in. Good luck! BTW, my S is at Carnegie Mellon.</p>
