In most cases, if a course number has changed recently, the
previous course number is given 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.
