The Psychological & Brain Sciences BS major has pre-major & full major rules and regulations. Please also review the major requirements above.

Pre-Major Rules:

Admission to the major is contingent upon fulfilling the following requirements:

• 1) At least a 2.7 UC GPA in Area I. 
• 2) At least a 2.0 UC GPA in Area II.
• 3) All courses must be completed on a letter grade basis. 
• 4) No courses with a grade lower than C- in Area I & II.
• 5) Not more than one course with a C- in Area I & II.
• 6) Students must submit a departmental Change of Major packet to advising@psych.ucsb.edu for admission to the pre-major and full major. 

Major Regulations:

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.

To declare for the Pre- or Full PBS BS major, students must submit their “Change of Major” (CoM) paperwork (2 items total, instructions in documents below) to advising@psych.ucsb.edu. 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 3-6 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(s) (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.

Pre-PBS BS transfer students are encouraged to have completed at minimum 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 a course evaluation to determine if the material is an acceptable substitution for major credit.  Instructions for a course evaluation are located under the “course information” tab.
