What are Prerequisites and are they different then Co-requisites?
Yes, prerequisites and co-requisites are indeed different. A prerequisite is one or more course(s) which must be completed prior to enrollment in another course, whereas a co-requisite must be completed at the same time (in the same term) as enrollment in another course. For instance, PSYC 345 – Social Psychology lists PSYC 205 as a prerequisite, which means that PSYC 205 must be completed prior to enrollment in PSYC 345.
