<p>I had a question: On ACES registration, it says you need a 3, 4, or 5 on the AP Chemistry Exam to take Accelerated Chem, but on the T-Reqs AP Credit page AP</a> Credit and on the Duke Department of Chemistry page it says you need a 4/5 to take Chem 23L. Which one is right?</p>
<p>ur allowed to take it without ap credit...those are just recommendations</p>
<p>you can take it without any AP, my brother went to duke</p>
<p>even if u have a weak background in chem?</p>
<p>but want the challenge</p>
<p>If you want the challenge, go ahead and take it. Just know that it's definitely challenging, especially for someone with a weak chem background.</p>
<p>Just because you can, doesn't mean you should.</p>
<p>He did say he wants a challenge...</p>
<p>You would probably get destroyed in Chem 23 without having taken AP chem.</p>
