<p>My son is a high school junior. He will be applying to UNC-Chapel Hill in the fall (early action). I was thinking he should wait until Senior year to take math & English SAT II's since he will have had more instruction in those courses. It was my understanding that you want to take the subject test when you have completed that course of study (like Biology or History where he will not have any more). UNC says they don't require SAT II's and that it's for placement only. Is that to be believed?</p>
