I'm afraid I don't understand much of this - I have not had the time to look it up. These are different kinds of exams that make you eligible for college? I assume they are open for high school students? And how can you get college credits from an entrance exam? From what I read I thought your university credits worked like ours do, where you get credits from passing uni courses, and certain combinations of credits might lead to a degree, but then you actually have to take the course first...
