You will receive a grade of satisfactory audit or unsatisfactory audit but no credit. Payment is the same as for a credit class. Professors will expect you to attend class and to be prepared. If you think you already know the material in a course you are required to take, ask the department chair for a challenge exam. Or, of course, you may be told you have to take the course anyway.
Exceptions are lab courses wherein one credit hour equals two to four class hours per week.
The average number of credit hours for a one-semester course is three. To graduate with a bachelor's degree, you will need anywhere from 130 to 139 credit hours, depending upon your chosen major. The cumulative GPA is similar to semester GPA, except it is an average over your entire Tech career. Students with academic scholarships should refer to the New Mexico Tech Catalog for specific GPA requirements. You are entitled to a degree audit on courses taken at New Mexico Tech.
