<p>Intro to Biology seems to be the most fundamental science course offered at Harvard SSP. However, its prerequisites includes both HS bio + chem. I have only taken bio, and physics (soph this year). Do you think I might have a really hard time catching up? or it doesn't really matter wether you've had chem or not?</p>
<p>I would wait until you have had Chemistry. While the course is introductory it follows a quick pace in 8 weeks.</p>
<p>On a similar question, anyone know if you can defer Intro to Biology with a Biology A-Level? Or do I need to take an additional placement test?</p>
