Great. Your GPA is good and your course rigor is okay. Nevertheless, you may want ro bring up your test score a bit. UMich does not superscore. Even if it did, your score is only around admission average. So you chance would be not far off from the OOS admission rate which is around 20%.
I think your chances are excellent. Your course rigor, excellent gpa and athletics balanced with strong volunteer work look very good. Try the ACT…sometimes kids with strong science get a bit of an advantage with the ACT.
Your Math score is near admission average while your reading is at 25th percentile. So it is likely a reach for you from OOS. Are you planning to retake SAT?
