AP/College Course Credit for ECE

Hi everyone- I’m a high school senior, and I was accepted to electrical and computer engineering at CMU. If possible, I want to graduate in 3.5 years, and I’ve taken/am going to take the following AP exams:

• Calc AB/BC (20 credits)
• Comp Sci A (12 credits)
• Physics C Mechanics (12 credits)
• Chem (10 free elective credits)
• Stats (9 free elective credits)
• Env Sci (9 free elective credits)
• Gov (9 free elective credits)
• Lit (9 free elective credits)
• Lang (9 free elective credits)

Assuming all 5s, this adds up to about 96 credits fulfilled with AP exams. 379-96 credits = 283 credits needed. Averaging 90 credits per year means I can graduate in ~3.5 years. Taking the max credits of 108/year, I can graduate in ~3 years. Is my reasoning correct?

Also, I’ve taken Multivariable Calculus, Linear Algebra, and Differential Equations as online concurrent enrollment at a local community college. Has anyone been able to get credit for these asynchronous online college courses?
