UMich does not superscore. What is your highest single sit score? For Computer Science, you may apply to either LSA or CoE. LSA would be a lot bit easier than CoE to get in. However, your SAT is near the 25th percentile of admission even with superscore. Your GPA is around the admission average for LSA but below average for CoE while your course rigor is good. Considering the low admission rate from OOS (20% or less), UMich would be a low reach to reach for you.
