Declaring Your Major

Back to Major Information

Qualifying for the Major

Students who began their studies at UCSC in Fall 2009 or later must qualify to declare a Physics major.

To qualify for a Physics BS, Applied Physics BS, or Astrophysics BS, major students must complete PHYS 5A/15A, PHYS 5B, and PHYS 5C/15C (or their equivalents), with a cumulative GPA of 2.70 or greater.

NOTE: At least two of these three courses must be passed in the first attempt.

Students may petition to declare once they have successfully completed the courses required by the qualification policy.

Students who do not meet the qualification policy may appeal. For more information, visit our Appeal Process page.

Students with 2.67 GPA Probation Process

For students with 2.67 GPA, there is a standard probation process. Students who take PHYS 5D in the Fall quarter and get a grade of B or better will be considered eligible to declare a Physics major. Students who receive a grade of B- or lower will not be eligible, but will still be able to appeal the disqualification.

Double Major Policy

Students interested in pursuing multiple majors within the physical sciences may NOT declare the following combination of majors:

  • Physics & Applied Physics
  • Physics & Physics (Astrophysics)
