it is fine to use the College Board’s Score Choice option or the equivalent offered by the ACT.
How to report your test scores:
We recommend that you simply self-report your highest scores

SAT Subject Tests are optional. Because SAT Subject Test scores can highlight your areas of strength, we welcome the self-reporting of these results in your application. If you have taken a subject test more than once, it is fine to report your highest score
