<p>I got a 5 on the AP calculus BC and went straight into calc 3 and did perfectly fine. But then again I’m very mathematically inclined and I had taken courses like linear algebra and discrete mathematics before going into calc 3. Your mileage may vary.</p>
<p>In engineering, your schedule is pretty crowded anyway, so any relief from it (by skipping a semester of a course) is fairly valuable. Plus you get to move on and learn new interesting stuff and not just rehash old stuff.</p>
<p>However, if you think you’re not ready, then it’s perfectly fine to not waive calc I or II and take them first. Remember, it’s much better to take calc I and II than to take calc II twice :)</p>
