Are Subject SATs recommended with ACT

Hi everyone,
I am a long time lurker but posting here for the first time. I wanted to see if Duke would like to see Subject SATs inspite of having a strong ACT score. I also have a strong SAT score which I plan to submit also. However if I do not submit any Subject SATs is it still ok, will I be at any disadvantage at Duke ?
Thank you so much for your opinions !

it is not a disadvantage at all and most times they don’t like extra material, especially cause ur ACT already proves your a viable candidate: Duke does not "EXPECT or require sat subject tests for students who have taken the act)

Thank you. Are you quoting this from somewhere, have you seen this anywhere “Duke does not Expect or require SAT subject tests for students who have taken the ACT” ?

"If I take the ACT, can I also submit SAT Subject Tests?

Although we do not require or expect SAT Subject Test scores from candidates who take the ACT, we do accept them and will consider them as an additional demonstration of subject proficiency."

Also this:

"If I take both the SAT and ACT, do I need to send both scores to Duke? How does Duke consider multiple scores?

We will always consider your highest score regardless of test type or test date, and you are welcome to send us SAT scores, ACT scores or both. Applicants may choose the Score Choice option for the SAT and choose to submit scores from specific ACT test dates. We do NOT require applicants to submit all of their test scores–just the ones necessary to fulfill the testing requirement."
