Useful subject tests?

<p>Can you take an SAT test that has nothing to do with the university program you’re applying to?
I think I could get a high mark in a certain subject test because of strengths in that area - but I’m not interested in enough to apply in university to. Do you think it would matter to take a test to get a high mark among the 3 subject tests? or perhaps to show I’m well-rounded to the adcoms?</p>

<p>Thx!</p>
