<p>Recommend you retake the ACT and SAT both - try to get at least 33 on the ACT and increase your reading score to 700. With those you are clearly in the 20k-24k area.
Keep in mind UM’s cost of attendance this year for entering freshman is closing in on 60k, assuming you’ll live on campus. So, even with a 24k scholarship, you’re looking at maybe ~34k out of pocket for the first year. Could be less depending on several other factors (additional merit scholarships & grants from UM, outside scholarships, need for a computer, where you buy your books, etc).</p>
