Prerequisites for CSE Undergraduate Classes
Updated May 25th, 2023
Granting exceptions to prerequisites is rare and requires documentation of extenuating circumstances.
*An assigned letter grade of "D" is considered sufficient for meeting a course prerequisite unless otherwise noted.
*An assigned letter grade of "F", "NP", or an incomplete in a course are NOT considered sufficient for meeting a course prerequisite.
Students who need courses for their CSE major graduation requirements have priority enrollment. Petition approval does not give priority enrollment in the class.
***For courses restricted to certain academic levels or majors, all other students will be allowed as space permits. Students may use Enrollment Authorization System (EASy) to request clearance to be able to enroll/waitlist. These requests will only be reviewed if there is space in the course***
Undergraduates will receive priority for undergraduate courses. Graduate student requests to enroll in undergraduate courses will be reviewed at the end of week 1 of the quarter and only after all undergraduate requests have been processed.
Students may use the following ^ for CSE course prerequisite substitution purposes (no petition required, Enrollment Authorization System (EASy) request may be required if not explicitly listed in the approved course list):
^CSE 20 - MATH 109 or MATH 31CH may be used
^CSE 21 - MATH 184 or MATH 188 or MATH 154 or MATH 158 may be used
If you are using MATH 31CH for a change of major application, you must submit a petition.
