                          &nbsp; &nbsp; ACCT 104 (B)

                          <br>The above example means 'The student must take ACCT 104 (earning a B or higher).  They must also take EITHER ACCT 101 or ACCT 102.  Finally, they

                          Take note in this example that if the student takes only ACCT 104 and ACCT 101, then they will have satisfied all of the prereq requirements, since ACCT 101 is listed
