Considering a Double Major in Math? Here is What You Need to Know

Before deciding to pursue a double major, it's important to understand the requirements, timing, and policies involved.

⚠️ This page is intended to help you evaluate whether a double major is a good fit for you. It does not replace a thorough reading of official university policies.

Understand the Rules: There are specific procedures and a limited window in your academic timeline during which declaring a double major is typically allowed. It is very important to familiarize yourself with all Double Major policies, which are outlined on the How to Declare a Double Major (Undergraduates) webpage and in the General Catalog. 

Tip: Pay close attention to Page 2 of the Double Major Petition, which outlines essential rules and eligibility requirements. 

What Does It Mean to Double Major?

When you double major at UC San Diego, you complete all requirements for two separate undergraduate majors.

Keep in mind! A Double Major is not synonymous with a Joint Major.

A joint major is like two half majors. The Joint Major in Mathematics and Economics, for example, has roughly a 50/50 split between the two departments. A Double Major involves the completion of both majors and their full requirements. 

Ask Yourself These Questions 💡: Double majoring can be a rewarding path, but it’s not for everyone. Take time to reflect honestly. Here are some questions to consider:

• What will my two majors be, and why am I choosing them?
• What Math major am I considering? How many upper-division requirements does it have? 
• What do I hope to gain by double majoring?
• Will the added workload affect my GPA or academic performance?
• Will a double major help me reach my career goals?
• Will double-majoring lengthen the time it takes for me to finish undergraduate school? If yes, is the extra cost worth it?
• Would I be better off excelling in one major and then pursuing a second degree in graduate school instead of doing a double major?

Write down your answers. If you’re still uncertain, speak with departmental advisors and faculty. While they won’t make the decision for you, they can help you weigh your options and offer guidance.

Think Double Majoring is for you? Here's How to Get Started:

• Review Major Requirements: Start by reviewing the requirements for each major. You can find the details for Math majors in the General Catalog. 
• Prepare Your Documents: You'll need to complete the following documents (all must be submitted as PDFs): 
  • Double Major Petition form (PDF)
  • Academic Planning Worksheet.
  • Statement of Purpose: Write a brief statement explaining how your chosen majors and courses work together to support your current goals and future academic interests. It cannot be an email, it must be a written PDF document. 

• Submit Your Materials: Email all required PDF documents to math-advising-g@ucsd.edu. Please allow 2-3 business days for an advisor to review your submission.
