The academic calendar for each semester is provided in the front of the current Course Schedule; there are also web versions. The following information is generally true during each new long semester. Summer courses are subject to a somewhat compressed version of this procedure:

1. Adds/Drops before the 12th class day: During the first four (1-4) class days, students may add and drop courses using TEX, the Telephone Enrollment eXchange. During days five through twelve (5-12), students may drop courses by phone, but must go to the department offering the course to seek permission to add a course. Be advised that some departments do not allow adds/drops after the fourth class day. For those departments that do allow adds/drops, the add-transactions before the twelfth class day will be processed by terminal in the respective department. Students who wish to add a class after the twelfth class day will be required to see a counselor in the Student Division of the Dean's Office and provide justification for the proposed change. The student must have written permission and documentation of class attendance from the instructor.
    
2. Dropping a course after the open Q-drop period: After the end of the fourth week of class, and until the deadline for dropping courses, a student wishing to drop a course will ask the instructor to complete a drop form that assigns a Q or an F. The symbol Q indicates an average of C or better at the time of the drop, or that no grade has yet been assigned, or that due to the student's performance and the nature of the course, no academic penalty is in order, or that for documented non-academic reasons, no academic penalty is in order.
    
3. Deadline for dropping a course: For the Spring 2004 semester, the deadline for dropping courses is 29 March. After the deadline, students are not allowed to drop or to withdraw from school for academic reasons. If a student has compelling nonacademic reasons to drop or withdraw, a written appeal must be presented in the Student Division of the Dean's Office.

In addition are the following Computer Sciences Department rules for adding Computer Sciences classes:

• instructions for CS majors (undergraduates and graduates)
• instructions for non-CS undergraduates
• instructions for non-CS graduate students
