Two things about CMU: First, they only look at grades 10-12, so your lower 9th grade GPA won’t be an issue.
Second, CMU offers a BS in data science through the Department of Social and Decision Sciences in Dietrich. I have to imagine that the acceptance rate for this program is higher than for a student with your profile for computer science. Look at both programs carefully to see which is a better fit for your interests. Don’t apply to data science if it isn’t what you want because they will suss out people who actually want CS. But if data science is your preference, that could be an ever so slightly easier admit than CS.
