<p>if you get a 4 or a 5 on a test, doi you HAVE to test out of the class? or can you have the option of retaking it...</p>

For the most part it's really not even something you have to think about until you choose a concentration (major) second semester, second year. A possible exception could be language. Even putting the AP aside, if you've taken let's say two years of a language but feel uncomfortable in it, it might be difficult to sign up for an intro. And if you've taken more they probably they might discourage a lower level class.</p>
