In the 1987, I took the afternoons of my senior year and went to the local community college since we got 3 credits a semester free and paid only $15&#x2F;credit after that.  Students are still doing that here (now its considered dual HS &#x2F; College credit).  AP classes just don&#x27;t make sense in that context, and I would imagine if a student in a podunk high school on the reservation in the 80&#x27;s could do that, it must be more common at decent high schools.
