Do colleges only consider your highest ACT?

I’m freaking out a bit because I just realized that I accidently sent both of my ACT scores to my top choice school, UW-Madison. On my first ACT, I got a 29 composite score. On my individual scores, I recieved a 32 in English, 23 in math, 26 in science, and 35 on reading. When I took the ACT again, my composite score went down to 27 - 33 in English, 25 in math, 22 in science, and 26 in reading. I’m worried because there is obviously a lot of variation with some of my scores (specifically my reading!). Will colleges only consider my ACT with the highest composite score? How much will they take into consideration my second ACT score/will it affect my addmission chances?

Thanks in advance.

This should be searchable on your target universities websites.

This is from Madison’s website.

“UW–Madison encourages students to submit all exam scores. It is a benefit to see your complete testing history as part of our comprehensive review, and since we will only consider your highest score (by test date), there is nothing to be gained by suppressing scores through Score Choice. However, applicants are free to use the College Board’s Score Choice option for the SAT and/or the similar option offered by ACT.”

@cshell2 thank you so much! I was looking at UW-Madison’s website but did not come across that…thank you!
