<p>are there classes that offer more than 1 credit. from what it seems all classes are 1 credit</p>
<p>some classes have lecture + lab and are 1.5 credits, and some accelerated language classes are 2 credits</p>
<p>still, I'd say 99.7% of courses are 1 cu.</p>
<p>Also a few classes (a few marketing classes come to mind) are 0.5 credits, and that's because they only last for half a semester. There's only like 10-15 of these though.</p>
<p>Penn's system is the course unit system, as opposed to the semester hour system. Personally I'm not a fan, but what can you do... </p>
<p>A typical 1 c.u. course is the equivalent of a 3 credit course anywhere else. It usually involves 3 hours of class. Biology, chemistry, and physics classes usually have a lab requirement and usually involve 3 hours of lecture, 1 hour of recitation, 1-2 hours of lab lecture and 3-6 hours of lab for a total of 1.5 c.u. (that seems unfair but meh). Many math courses (especially calculus courses) are 3 hours of lecture and one hour of recitation for 1 c.u. per semester. Introductory language courses are 1 c.u. and involve either 4 or 5 hours of class each week.</p>
<p>Some courses, including music performance courses, certain language programs and certain marketing classes are 0.5 c.u.; these include things such as University Choir, which may be taken either for credit or for fun. The music and language programs last all semester but have very little out of class work even though they often involve upwards of 4 hours per week of "class time," so that is why they are only 0.5 c.u.</p>
<p>In reality this stuff makes no difference. Whereas most schools have a roughly 120 credit graduation requirement, Penn's CAS has, generally, a 32 c.u. requirement. Some programs have more (some Nursing programs have 41.5 c.u.!), but yeah.</p>
