Psychobiology Major For Students Who Entered UCLA As Freshmen

Pre-Psychobiology Major Requirements

Students may declare the Pre-Psychobiology major once they have established a prep GPA by taking at least one prep course for a letter grade at UCLA and have an average prep GPA of 2.0 or higher.

All of the following Procedures and Requirements will be strictly enforced:

  • A C or better is required in Psychology 10, Psychology 100A and Psychology 100B.  A C- or better is required in all other preparation courses.  All courses must be taken for a letter grade.
  • An overall grade-point average of 2.0 (C) is required in the preparation courses.
  • All of the preparation courses must be completed by the end of summer quarter following the student's 3rd year.
  • Repetition of any preparation course more than once results in automatic denial of admission to the major.
  • Repetition of more than any two preparation courses results in automatic denial of admission to the major.

Students who fail to meet any of these preparation requirements will be changed from Pre-Psychobiology to Undeclared.
