University of Michigan sending SAT scores

<p>Hi,</p>

<p>I am applying to the University of Michigan and I was wondering if I needed to send in all of my test (SAT/ACT) scores? I didn't do so well on my SAT, but I wanted to send my SAT subject test scores. However, the collegeboard website said that University of Michigan also wanted me to send in my SAT score. I am using my ACT though, so I don't really want to send it and I'm not finding a clear answer on the website. If someone who knows could please tell me, I would really appreciate it!</p>

<p>Thanks!</p>
