The CaSB Pre-Major provides students with broad, foundational knowledge in the sciences–biology, chemistry, physics, and mathematics–plus an introduction to computer science.
All students must complete the Pre-Major coursework prior to admission to the Major.
CaSB Major Sheet
Please reference the CaSB Major Sheet for Pre-Major and Major course requirements, Concentration information, and Department policies.
NOTE: The CaSB Major Sheet is reflective of requirements for students entering the Pre-Major effective Winter 2020 and forward. For all students admitted to the Pre-Major prior to Winter 2020, please consult your Degree Audit Report and the CaSB Department Counselor for your Pre-Major requirements.

CaSB Pre-Major Course Planning
When planning Pre-Major coursework, students have different options for completing the mathematics/statistics, chemistry, physics, and computing requirements. Based on students’ choice of mathematics/statistics series and intended Concentration, students are advised to take certain courses. The decision tree below can help students identify course options.
When planning courses, students must be mindful of pre-requisites. The flowcharts below are meant to help students plan out Pre-Major coursework by depicting the requisites for each series. These flowcharts were last updated December 2019. Always check the Registrar’s Course Descriptions for the most up-to-date requisites.
All Pre-Major courses must be taken for a letter grade.
Students who receive a C- or below in a Pre-Major course must either repeat the course or petition to have the lower grade count for the Pre-Major. Students who receive 3 or more grades of a C- or below in Pre-Major courses may be dismissed from CaSB. Learn more about repeat policies and academic eligibility here.
Students are subject to any requirement changes in the Pre-Major and Major until they are officially admitted to the Major.
