AP Credits and Placement - Unwanted?

<p>With AP exams coming up and all, i was just wondering if any admits or current students could answer some of my questions on the worth of placing out of stanford classes.</p>

<p>I'll be able to place out of courses for about three of my AP exams, but i'm not sure if it will be worht it in the future. As a prospective ChemE major, i want to make sure i'm solid for science/math classes, and from what i've heard college calc and college chem are much more intense than in high school.</p>

<p>Assuming that it will probably be a little easier the second time around, should i opt to not place out of intro physics and math class (the AP courses i took) in order to learn the material better?</p>
