<p>I'm looking at the Chem 6B class and its prerequisites require chem 6A and math 10/20 A. So i have two questions </p>
<ol>
<li>since I got a 4 on my ap chem test I'm exempted from chem 6A. Does that mean the first prerequisite is fulfilled?</li>
<li>I'm planning on taking math 20A this coming fall, does taking a class concurrently also work for a prerequisite?</li>
</ol>
<p>Thanks!</p>
