Math Pathways
UCSD offers two calculus math pathways. Students start in the pathway based on their math placement and complete each successive course required by their major and/or college.
- The Math 10 calculus series is the pathway for biological and social science majors.
- The Math 20 calculus series is the pathway for Science, Technology, Engineering, and Mathematics majors.
Check your major to see which series you should enroll in.
Math 10 Series Pathway
The Math 10 series meets minimum requirements for biology and social science majors and meets the general education requirements for many of the UCSD colleges. Check with your major and college to ensure this calculus pathway meets the requirements.
