Question about AP exams and their importance???

<p>hi guys,
i heard from many sources that your AP exam grade doesn't matter at all in college admissions. Is this true? Which do you guys think would look better: a B in AP Biology with a 5 on the exam, or an A in AP Biology with a 3 on the exam?
I mean I heard that AP exam grades help you skip out of classes in college, but most Tier I schools only accept AP credit for like 1 subject, so whats the point of doing well on so many exams?</p>
