Should I take Workload Chemistry and Precalculus if I pass the exam?

<p>It has been 3 years since I took Chemistry, and my precalcus and chemistry are both not very good. I passed the chemistry exam and precalculus exam. Should I take Precalculus instead of Calculus and Workload Chemistry instead of Chemistry?</p>

<p>As far as I know, if you pass the placement exams, you cannot take precalculus or workload chemistry.</p>

<p>I'm pretty sure Workload Chemistry just teaches you the information you need to pass the placement exam. You should take 2a. As far as math goes, I didn't find 21a very difficult. Then again, I had taken AP Calc AB in high school.</p>
