Claremont School Situation: The Claremont School course catalog reads as follows: “To enroll in CIS 288, which is an advanced course, a student must complete two prerequisites — CIS 110 and CIS 286. A student who completes either one of these prerequisites and obtains the instructor’s permission, however, will be allowed to take CIS 288.”
