I don't really know how to word this very well, so it will all just be mixed and thrown around, just try to bear with me.
AP Courses are offered in most high schools for students to have an opportunity to take the advanced class so that (s)he can get out of taking it in college and either take the next level class or not take the class at all. Now, most colleges today only accept a 4 or a 5 on an AP test for you to get the college credit and not have to take that class. For students who get the 4 or the 5, great. But for the student who gets the 3, which is passing, or lower, what's the whole point? That student might have just as well not taken the class in high school or taken a lower level class and get an A in that class instead of suffering through a whole year of work and tests and essays then not getting credit for the class they took. I don't see the point at all, it's kinda unfair. Another issue that I've noticed is that students either take an AP class for their GPA, they don't necessarily care if they pass the AP test or not. Others, on the other hand, take the class just because they want to "test" out of it in college and they don't want to do the work so they fail the class and don't get credit for it even if they get a 5 on the actual test.
So, what's the point of it all? Better yet, what's the reason for things being how they are.
