In most cases, if a course number has changed recently, the previous course number is given immediately below the title of the course with the following notation: (Formerly 00:000:000). Nevertheless, it is the student`s responsibility to read course descriptions carefully and, when in doubt, to check with his or her adviser or the appropriate department to avoid registering for a course that the student may have already taken. Credit is not given twice for the same course, despite a change in number and/or title.
