How to Add Classes

If you are a new or returning student, you must complete the other steps to apply and enroll before registering for classes. Once you've completed your application, assessment, orientation and met with a counselor, check your registration date by using your My Mt. SAC Portal. You may register for classes using your Mt. SAC Portal on or after your assigned date and time.

Prepare to Register for Classes

Log in to your Mt. SAC Portal to view your registration date and time. You will not be able to register before this assigned date and time.
Before you register, look at the Schedule of Classes or Search Online for Open Classes, and decide what classes you would like to take. Write down the Course Reference Number (CRN) of each class - you'll need it when you register - and be sure to pick a few back-ups, in case some of the classes are closed when you register.
As you're picking classes, be sure to check course prerequisites and corequisites. If a class has prerequisites or corequisites listed next to it, be sure you meet those requirements before you register for classes. Not sure what prerequisites and corequisites are? Check out our Decoding Registration Terminology section below, or, learn more about Class Eligibility requirements here.

How to Register with an Add Authorization Code

To add a closed class or once the class starts, you must attend the first class meeting and obtain an Add Authorization Code from the instructor. It is a 6-digit code. The Add Authorization code can only be used once and has an expiration date. Be sure to use the code on or before the expiration date. Failure to do so will prevent students from adding the class. You must be eligible (have the appropriate prerequisite) for the class. If the course has a required prerequisite.

Decoding Registration Terminology

We make the registration process as easy as possible for Mt. San Antonio College students, but we know that some of the terminology can be confusing. Here are explanations of some terms you might come across as you go through the registration process:

New Student: A student who has not attended Mt. SAC before - even if you've attended another college, trade school, or a local high school, you're a new student to us.
Returning Student: A student who has attended Mt. SAC but, for any reason, has missed two or more major consecutive semesters (for example, Fall 2014 and Spring 2015 are considered two consecutive major semesters).
Continuing Student: A student who has attended and been enrolled in classes in Mt. SAC within the past two major semesters (Fall and Spring Semesters are considered our "major" semesters and Winter and Summer terms are considered "minor" or "mini" intersessions).
Prerequisite: A course or experience (e.g., a test) that must be completed before you take certain classes. If a class has a prerequisite, it will be noted in the course description in the Schedule of Classes and in the College Catalog. If you register for a class without meeting the prerequisite requirements, you may be dropped from the class.
Advisory prerequisite: A course that is not required for enrollment, but is recommended to help you succeed in the course.
Corequisite: A course that must be taken during the same semester as the course it is listed as a corequisite for. Corequisites are also noted in the course descriptions. For example, if you want to take Class A and you see in the course description that Class B is a corequisite for Class A, that means that you must take Class A and Class B in the same semester - so you must be sure to register for both. If you register for a class without meeting the corequisite requirements, you may be dropped from the class.
Special approval: An additional approval (override) that is required by the department/program.
Credit classes: These classes are generally courses designed for students who are interested in earning college credit units towards a degree or certificate. Students who take credit courses receive a letter grade (A, B, C, D, F, I, NP, or P) at the end of the semester.
Continuing education noncredit classes: Our Continuing Education program offers noncredit courses for students who want to develop skills for college, their career, or just to enrich their lives. Noncredit courses include Adult Basic Education, Adult High School Diploma, ESL, Skills Certificates, noncredit Vocational Programs, and more. Noncredit classes do NOT count toward degrees. Upon completion of a series of required classes, students can earn a noncredit certificate in a variety of Adult Basic Education, ESL, and vocational areas.
Continuing education fee-based classes: Our Continuing Education program also offers fee-based noncredit courses for recreation, personal development, and professional development. Fee-based classes are self-supporting and are not funded by taxpayer dollars. The fees are based on the instructor’s salary, enrollment, duration of the class, and administrative and operating costs.
