Class Schedule Terminology

TMCC Class Schedules should be used in conjunction with the TMCC College Catalog which contains course descriptions and degree program information. Students are responsible for being familiar with the regulations and policies contained in the Catalog.

Course Number

This 3-digit number, appearing after the course subject, designates the numerical identifier of that course.

TMCC has the following course numbering system:

  • Remedial/developmental courses: 001-099
  • Lower-division courses: 100-299
  • Upper-division courses: 300-499

Remedial/developmental courses do not count towards a certificate of degree and are not financial aid eligible.

Class Number

A class number is the 5-digit number that identifies each class and is used to enroll in specific class sections through MyTMCC.

Subject (Prefix)

The course subject, also called the course prefix, is the alphabetic designation for the course subject.


The course section is designated by the 4-digits after the course subject and class number. It refers to the specific class date/time option.

Corequisites and Prerequisites

Corequisites are courses that must be taken at the same time as another course. For example, some science lecture courses may also require that students enroll in a lab section, such as PHYS 180 and 180L.

Prerequisites are test scores and/or courses that must be completed with a passing grade prior to enrolling in a specific course. For example, students must either test into ENG 102 or complete ENG 101 with a passing grade prior to enrolling in ENG 102.


Most classes are held at TMCC's Dandini Campus (RDMT, SIER and VSTA buildings), Meadowood Center (MDWS and MDWN buildings), Applied Technology Center (EDSN), and Pennington Health Science Center (HSC).

Other classes are held at various locations throughout the community. Check your class listing for location and verify the address.
