<p>Taking subject tests are optional at Stanford. But is there anyone who got in without taking subject tests?</p>
<p>Probably most people applying to Stanford are also applying to other highly selective schools, and many /most of those require them. So, my guess is that most Stanford applicants take 2 or more.</p>
<p>Yes, if you take the ACT, you are not required to submit subject tests. Just be sure that you have a good ACT score.</p>
<p>I would definitely suggest taking them, especially if you want to highlight a specific area that you a have special talent with.</p>
