allowing it (and its tuition) to be skipped
LOL, oh you're serious, let me laugh harder. If you think skipped courses due to AP credits reduce the number of hours needed to graduate at the vast, vast majority of schools you're mistaken. No, it will just let you skip an intro course and fill the hours requirement for your major for something a little less dull.
When I went to college orientation (about 15 years ago), while all of the other incoming freshmen were taking placement exams, I was listening to the school's pitch to the parents. Why? Because I had to take absolutely 0 placement exams.
Based on my AP test scores I skipped:
2 quarters of Chemistry (both required for my major, meaning I did not have to take any chemistry at college) - AP Chemistry 5
2 quarters of Calculus (going straight into the 3rd of the 4 quarter Calculus cycle required for my major) - AP Calculus BC 5
1 quarter of English (required for my major, I had to take 1 English composition course) - AP English 4
1 quarter of Physics (required for my major, I had to take 1 additional Physics course) AP Physics - 4
2 quarters of American Social Studies (required for a General Elective category for my major) - AP US History 5, AP US Government 4
Essentially, these credits saved 2 quarters of real college work toward my degree.
I also received in addition to the above:
5 credit hours Math (the "intro" class to prep you for the calculus series)
15 credit hours Spanish - AP Spanish 3 (I didn't even take the AP class, just the test)
10 credit hours low-level Comp Sci - AP Computer Science AB 5
These additional credits meant that, following my 1st quarter at college, I had enough earned credits to be considered a Junior as far as class rank went, which was nice for having advantages for priority in class enrollment, football season ticket, dorm selection, etc.
Oh, and by the way, this was for an Electrical Engineering degree.
