Yes, be sure to understand how AP credits works and what it means in terms of college tuition.
More often than not, while it allows you to start at a next-level course, frees up time to take electives, provides an option for a lower load semester, etc., it doesn’t actually allow you to graduate earlier. There are major-specific course sequences to take Soph and Jr years, and then Senior project courses that are all pre-requisites for each other. This is all very major-dependent x Engineering, Computer Science, STEM in general in particular.
And since you pay a flat rate by semester, not by credit, there really aren’t cost savings.
At the same time, some of the above-mentioned majors almost require Summer, Winter Break, or even 9th semester studies, which brings a cost, and AP credits avoid that.
So just be sure to understand the implications. 7 AP courses while filling our applications, making campus visits, will be quite time intensive.
Fwiw, my D has 20-ish credits coming in and still took 2 summer courses to be on track to graduate in 4 years in Engineering because she added an Entrepreneurship and Innovation Certificate.
