shot or pass

[NorthSide]

I'm looking for the specific rule in the book:

HS - A1 throws an alley-oop pass from the 28-foot line toward the basket for A2. Ball goes into the basket. 2 or 3 points?

NCAA - Same situation, however, ball doesn't go into the basket, yet hits the rim. If offense team retains the carom, does the shot-clock reset? What's the ruling if the ball does go into the basket? 2 or 3 points?
