Placing out -- AP

<p>okay, this may be a dumb question, but the whole distribution requirements thing confuses me. If i have a 5 on eng lang, and 5 on eng lit … those do not count for credit? do they just mean that I get placed in a harder english class? If i have 5’s on world, euro, and US history - does that mean I never have to take a history class in college if my major is in science? and a 3 or 4 on chem would just effect what class I was in, right? or would I actually get a credit for it?</p>
