<p>a sophomore may choose to take 6a for many reasons. sudden change of heart, changing majors, need it for a GE, whatever. one of my suitemates started the chem6 series and she was a sophomore. my roommate next year (soph) is starting the chem6 series so don’t think that it’s only a freshman class. and if you haven’t looked at the schedule of classes, a bunch of non-freshmen have signed up for chem6a.</p>
