Sending multiple ACT scores

I’m having trouble deciding if I should send my best score, or all of my ACT scores because I had better sectional scores on different tests. On U of M’s website, they say that there’s really no penalty to doing this - they’ll evaluate all of my highest sectional scores without penalty for lower scores on other sections - but I’m still not sure. What should I do?

My unofficial advice. If you don’t have any really awful scores…go ahead and send them all. If there are a couple embarrassing scores, send the set that most supports your major. For example…if you’re going for engineering, send the set with the best math and science.
