I agree, the new site is very difficult to navigate.
That page shows that you can validate out of history for taking the World, US, and Euro AP exams. If I successfully make 5s in all five of those APs and validate out of them, then where would the Academy put me? In a senior history class or would I take an elective?
Since the history example was brought up...
If you validate with AP US History, you would only need to take 1 American History class instead of 2. However, the American History classes are only required for history majors.
