Declaring Your Major

Make an appointment with your faculty mentor and fill out the Petition to Declare Major form. 

Please meet with your major adviser Maria Nishanian to create your academic plan

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, Phys 5B, and Phys 5C 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.

Students with 2.67 GPA Probation Process

For students with 2.67 GPA, there is a standard probation process. Students can take Physics 5D in the fall and can get a grade of B or better, they will be considered eligible to declare physics. If they get a grade of B- or lower, they will not be eligible, but would 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:

  • Biology (BA, BS, bioeducation concentration, or minor) AND any other biological sciences major
  • Any combination of two Ecology & Evolutionary Biology majors:  Ecology & Evolution, Marine Biology, Plant Sciences, or Environmental Studies/Biology combined
  • Molecular, Cell & Developmental Biology AND Neuroscience major
  • Molecular, Cell & Developmental Biology AND Biochemistry & Molecular Biology major
  • Biochemistry & Molecular Biology AND Neuroscience major
  • Biochemistry & Molecular Biology AND Human Biology major

Should you choose to double major in two science majors, you must qualify for both majors.

Students electing a double major may not use the online petition to declare, but must make an appointment to meet with their major advisor.
