Some courses offered at SCC require either a prerequisite or corequisite (or both) before enrolling. All prerequisites or corequisites are identified in the college catalog in the course description section.

If you have already completed an identified prerequisite at another college, proof of prerequisite (report card or transcript) will be required. An advisor or registration assistant can verify that the prerequisite has been fulfilled.

Prerequisite Defined

A prerequisite is a condition of enrollment that you are required to meet prior to enrolling in a course. These prerequisite courses provide the minimum level of proficiency knowledge needed for successful achievement in the next level course.

• You must obtain written approval of any exceptions. Exceptions to prerequisites may be made by the student talking with the course instructor and having them sign the registration form. This form must then be returned to the Registration Office.
• If you are taking or just completed a prerequisite course for which SCC has not yet received grades, you may register for the advanced course; however, you must withdraw from the advanced course if the grade you received does not satisfy the requirement of "successful completion."
  
  Example: Successfully complete English 101 before enrolling in English 102.

Corequisite Defined

A corequisite is a course that needs to be taken concurrently with another course. This is very typical with science courses.

• You must sign up for both the course and any corequisite. If you later wish to drop the course, you must also drop the corequisite. If you fail the course, you may be allowed to repeat that course without retaking the corequisite. However, you will not be allowed to advance in a sequence of courses until both have been successfully completed.
  
  Example: BIO 101 and corequisite BIO 103 (lab)
