Alpha Numerics For Dummies

Of course, some schools have to make up their own rules! At UPenn, in some departments (like economics and anthropology) the lower level courses are numbered 1-99. Upper-level is 100-199, and anything 200 and higher is for seniors in the major and may also be considered graduate-level. In other departments, the conventional 100-200-300-400 system is used. UPenn showed utter disregard for my EC advisor's sanity. :p
