<p>Most colleges have a footnote somewhere saying that two math SAT subject tests does not count as two tests. There are some colleges where you don’t have to decide on engineering when you apply, at most of those colleges you could take no math or science subject tests, but it is true that most engineering schools have more specific requirements. (Generally Math 2 and Chemistry or Physics.) </p>
<p>Both my kids chose to go the well-rounded route and both had applied to at least one college that required 3 tests. S1 had math 2, physics and US History. S2 had Lit, US History and Biology.</p>
<p>My older son had 3 800s on subject tests - one sitting. Did it help him? I’m sure it did, he got into Harvard, CMU and got nice merit offers at two safeties. But of course if he’d only applied to the four colleges that didn’t accept him, I could argue it didn’t help him at all. That would be silly. Having seen his whole application though, I’m pretty sure it was his one-sidedness and some less than stellar essays on supplements that probably did him in.</p>
