Psychological & Brain Sciences Major
The Pre-Psychological & Brain Sciences BS (Pre-PBS) & Full Psychological & Brain Sciences BS (PBS) majors are designed to guide students through the requirements of a Bachelor of Science degree. First, students work on pre-major courses to qualify for joining the full major. Should they meet the requirements of the pre-major, students must then declare full major to complete their PBS BS degree.

Pre-Major Rules & Major Regulations
The Psychological & Brain Sciences BS major has pre-major & full major rules and regulations. Please also review the major requirements above.
Admission to the major is contingent upon fulfilling the following requirements:
- At least a 2.7 UC GPA in Area I.
- At least a 2.0 UC GPA in Area II.
- All courses must be completed on a letter grade basis.
- No courses with a grade lower than C- in Area I & II.
- Not more than one course with a C- in Area I & II.
- Students must satisfy Area I & Area II and GPA requirements prior to the completion of 144 total units.
- Students must submit a “Petition to Change Major” to the departmental main office (1814 Psychology East) for admission to the pre-major and full major.
Enrollment in PSY 110 or higher courses is contingent upon satisfying pre-major requirements.
- Check the UCSB General Catalog for the prerequisites to all listed courses. Pre-reqs are strictly enforced, no exceptions.
- Up to 8 units of PSY 199P may be taken for major credit. All other major courses (prep or UD), including courses applied to the major from other departments, must be completed on a letter-grade basis.
- At least 2.0 overall UC GPA in all upper-division major courses and all courses (prep and UD) for the major, including courses in excess of minimum requirements.
Declaring pre- or full Psychological & Brain Sciences BS
To declare Pre- or Full PBS BS major, students must submit their “Change of Major” (CoM) paperwork (3 items total, instructions in documents below) to the PSYCH EAST main office. Pending qualifying grades posted on a student's transcript, this paperwork will be processed by the PBS department and forwarded to the Office of the Registrar (please allow 2-3 weeks for processing). Change of Major status will be updated via a student’s GOLD portal and will “unlock” access to PSY classes. For those switching from pre- to full major, please turn in your request from Pre-PBS BS to Full PBS BS while you are enrolled in your final pre-major course (CoM paperwork is due by finals week and will be processed after final grades are posted).
PSY 10A and 10B are limited to Pre-PBS BS standing students.
PSY 110+ courses are limited to Full PBS BS standing students.
Transfer Student Info
Pre-PBS BS transfer students are encouraged to have completed a minimum of one year of General Chemistry. The General Biology series is encouraged but not required. Additional pre-major courses that can be completed prior to transfer are Intro to Psychology, Calculus, and Statistics. Note: CC grades do not factor into UC GPA.
PSY 10A & 10B are only offered at UCSB (there is no CC equivalency).
Use assist.org to identify California Community College course equivalencies to UCSB courses. For coursework transferred from CSU/private/out of state schools, students must request an evaluation to audit the material as acceptable substitution for major credit. Instructions for an audit request are located under the “course information” tab.
