More about Peer Advising

Faculty Advisors

The Undergraduate Student Services Office assigns a faculty member as your major advisor during the declaration process.

Develop a good student/advisor relationship.

  • Your advisor can assist with questions about coursework to fulfill requirements and career goals.
  • He/She can be a good mentor for your present and future goals.
  • Share your future goals with your Faculty Advisor, even if they might change, including what has inspired you to establish such goals.

We also encourage you to meet and talk to other IB faculty, particularly those conducting research in an area that interests you.

Graduate Student Instructors (GSIs)

Establish and maintain contact with your Graduate Student Instructor (GSI). GSIs can be supportive in helping students achieve immediate and long-range goals. GSIs can also be a valuable conduit to earning a research opportunity for you. Add them to your network of resources and information here at Cal.
