Science Sequence Regulations

Departments in the College discourage students from registering for the next course in a continuing science sequence if an appropriate grade level (“C–’’ or above) has not been achieved in the preceding course. It has been shown that students' success in such a sequence is directly related to performance in the preceding course. Students so advised are asked to seek assistance in their future program planning from the College Center for Advising Service and from their undergraduate advisors.

Science Sequence Minimum Grades

Students who are not permitted to continue in the sequence, but who wish to prepare themselves for further study in this area, are encouraged to consider auditing the course in which they had difficulty or re-registering for it. See the repeating courses and transfer credit pages for more information.

If students believe that mitigating circumstances caused them to do poorly, they can discuss their situation with an advisor in the College Center for Advising Services, who will help the student to complete an online petition.

Please review the grades earned by students who received permission to continue in a sequence after earning less than the required grade in the preceding course: Data from fall 2010 through fall 2021 semesters (pdf).
