Prerequisites or Co-Requisites
Some course descriptions stipulate that students must earn credit for certain course prerequisites before they can enroll. Prerequisites help assure that students have sufficient background in the subject to succeed in the course.

A co-requisite is a notation in a course description indicating that a student who enrolls in the course must also enroll concurrently in the listed co-requisite course unless that course has already been completed with a passing grade.

Under special circumstances the department chairman may allow a student to register for a course without the required prerequisite or co-requisite. A waiver of the required prerequisite or co-requisite does not affect degree requirements. Students who have been granted a waiver may earn needed credit through course substitution or credit by examination. Although students may receive credit toward graduation at San Jacinto College, if prerequisites are waived for certain courses, another college may not allow credit for such courses. If students do not follow prerequisite/co-requisite requirements, the College may withdraw them from the course.

Minimum placement test scores in reading, writing, and/ or mathematics skills are prerequisites for virtually every academic, developmental, and technical mathematics course. These prerequisites constitute a condition of enrollment in these courses for all students and cannot be waived. Footnotes in the Schedule of Classes and the course descriptions in the Catalog will indicate which courses have such prerequisites.
