1.  If I don't like one of my classes, is it okay to just stop going to class?
No, it's not okay. If you just stop going to class without dropping or withdrawing, you will almost certainly get an "E" in the class. You can drop a class through the end of the fourth week of classes on-line using WebReg in Student Link.
It is your responsibility to drop a class if you are not attending it.

After the fourth week of classes, your instructor must sign a drop form for you to withdraw from a class.
If you are failing a course at the time that you withdraw, your instructor may award you an "E" instead of a "W."

After the eighth week of classes, the only way to withdraw from a course is to file a late change petition.
You must be able to document circumstances beyond your control for the petition to be considered.

Students in the Center for Exploratory Students can pick up late change petitions in room 103 of the Integrated Learning Center.

Students with majors in other colleges , see your college advisor.
Talk to an advisor if have any questions about dropping or withdrawing.

2.  How can I find out what the deadlines are for dropping and adding classes?
Dates and deadlines are provided in the General Catalog under Academic Calendar
and in the Schedule of Classes under Dates and Deadlines.

In order to add classes once school has begun, you must get an add/drop form signed by the instructor of the course you wish to add. After the first eight weeks of class, you must file a late change petition in order to add a class. There is no specific deadline for adding classes, but instructors don't usually let students add after the first 2 weeks of the semester because they would have a hard time catching up on what they had missed and therefore could be setting themselves up for failure in the class.

Please remember that any increase in the number of units you are enrolled in after the 21st day of classes will result in a $250 late fee.

3.  I dropped one class and added another class using a drop/add form.
How can I check to make sure that these changes in my class schedule were definitely made?
Every semester you should check your class schedule in Student Link to make certain you are registered for the classes you think you are registered for. If you drop and quit attending a class, you must check to verify that it was dropped from your schedule; otherwise, you might receive an "E" grade for the class. And if you are attending a class that was not added to your class schedule, you will not receive a grade for the class even if you completed all the assignments.

Keep your copy of the drop/add form and all other UA forms.
