So Classes are Full. What Do I Do Next?
How to Make Changes to Your Class Schedule
You can make the following changes to your course schedule by logging into
• Withdraw or “drop” from classes
• Add open classes or any class for which you have an Add Authorization Code (see the Add Authorization Code section
for instructions).
• It is your responsibility to know deadlines to add courses and to drop courses if you are no longer attending classes.
• Pay the required fee for any added class. Payment is due upon registration. Students who fail to pay for their classes
by the established deadlines will be dropped from their classes. These deadlines will be posted on the student portal at
my.mtsac.edu and on your Print Schedule/Receipt. Students who remain enrolled after the course refund deadline are
financially responsible for the payment of fees even if they drop the class or are dropped by their instructor.
• Drop by the course refund deadline on Print Schedule Receipt to qualify for a refund.
Adding or Dropping a Class (See schedule/receipt for add/drop date.
Each class has a unique date.)
To Add an Open Class:
• You may add open classes online at my.mtsac.edu.
• Once classes start, you must attend the first class meeting to obtain an Add Authorization Code if the class is no longer
available through the registration system. Instructors will add students depending on the number of open spaces in the
class. Please note: students on wait lists will be added before walk-in students. Being on a wait list does not guarantee
you will be given an Add Authorization code. You must attend the first class meeting.
• You must have your Mt. SAC registration appointment printout of your assigned date and time, along with a picture ID.
• You must be eligible (have the appropriate prerequisite) for the class. Prerequisites will be checked by the system at
the time you register for the class. If you are blocked from registering for a class and believe that you do possess the
appropriate prerequisite, or if you have a question regarding the prerequisite, call (909) 274-4415 for assistance.
• You must register for all add’s prior to the expiration date on the Add Authorization Code.
• You MUST have a picture ID to add classes in person.
