The Bachelor of Arts in Natural Sciences

Total Course Requirements for the Bachelor's Degree: 120 units

See Bachelor's Degree Requirements in the University Catalog for complete details on general degree requirements. A minimum of 40 units, including those required for the major, must be upper division.

A suggested Major Academic Plan (MAP) has been prepared to help students meet all graduation requirements within four years. You can view MAPs on the Degree MAPs page in the University Catalog or you can request a plan from your major advisor.

This degree is appropriate for students pursuing single subject matter preparation in Foundational-Level General Science. Thus it helps fulfill one of the requirements for admission into a single subject teaching credential program. See the Single Subject Matter Preparation Program in Science program.
This degree is also designed for students who are interested in science-related interdisciplinary careers such as science writing, law, or environmental policy. Students who choose this program should consult with their major advisor about career paths

General Education Pathway Requirements: 48 units

See General Education in the University Catalog and the Class Schedule for the most current information on General Education Pathway Requirements and course offerings.

This major has approved GE modification(s). See below for information on how to apply these modification(s).

  • GEOS 300 is an approved major course substitution for Upper Division Natural Sciences.
