CMU pre college APEA courses

Can some one please answer to my question, my daughter is a rising senior in a CA based school and she is interested in attending Cornelgie Mellon summer Pre-College APEA courses. Did anyone ever get accepted into the university after attending the pre college courses? Does it help in earning Admission at CMU? It’s lot of money and I am concerned.

Does it help? Probably, but not that much compared to GPA and SAT. I wouldn’t do it just for the sole purpose of increasing admission. It is more meaningful imo to find internships or do research when it comes to admission.
