<p>You can go to the College Board website to see what areas are covered in an SAT II versus the AP for the subject and determine if the school’s AP course has skipped something important, but there really is substantial overlap between most tests.</p>
<p>I stand by my advice to consider scheduling the SAT I and/or ACT in June after most of the school/AP season is done. You have to be well-rested and focused to do well on such a long and comprehensive exam. A student who is taking challenging courses should be focused on learning during the school year and that is stressful enough. </p>
<p>Son, a senior, and I worked out his testing schedule early in high school, before he knew how much tougher school gets as you take more honors courses, but he thinks it worked well. It’s not even October yet and he is already regularly operating on a sleep deficit from his heavy schedule. He was much more relaxed and better rested after he got his APs and finals out of the way last May and he thinks that helped his June test scores. He wanted to do well enough in June that he wouldn’t ever have to take them again. And he did.</p>
