<p>I do not see a problem with repeating classes if the college course adds to what was taught in a high school AP class (at some schools, from what I have heard from our high school’s graduates, the high school AP class was actually the more difficult class), but I also like the way some colleges have separate sections (often for fewer credits) for students who have already studied the material at hand at an AP level, but might not be ready to move to the next level at college. </p>
<p>So, a hypothetical intro gen chem class might have a 5 credit option and a 3 or 4 credit option, with the student placed in accordance with their background. The advantage to the student taking the option with fewer credits would be the opportunity to take more credits in something else. At the end of the year, students from each option would end up equally prepared to take the next course in the sequence.</p>
