How to Change Your Major in College

If you’re second-guessing your major, take comfort in knowing this is a normal part of the college experience. According to the National Center for Education Statistics, approximately 30 percent of undergraduates in associate’s and bachelor’s degree programs change their major at least once within three years of enrollment. About one in ten students changes their major more than once.

The reasons students switch vary widely. You may have discovered new interests through introductory courses, realized your original choice doesn’t align with your career goals, or found the coursework more challenging than expected. Students in STEM fields change majors at slightly higher rates (35 percent) compared to non-STEM students (29 percent). Mathematics majors have the highest switch rate at 52 percent, often because students discover related fields, like engineering, that weren’t as visible in high school.

The key question isn’t whether changing majors is acceptable—it absolutely is. The question is whether you’re making a thoughtful decision based on genuine fit rather than temporary frustration with a difficult course or professor.

Timing significantly impacts how smoothly your major change goes. If you’re within your first 60 credits (typically your first two years), switching majors usually has minimal impact on your graduation timeline. Most general education requirements overlap across majors, so courses you’ve already completed will likely still count.

At most institutions, you must declare a major before reaching 90 units or by the end of your sophomore year. At UC Berkeley, for example, College of Letters and Science students who haven’t declared by 90 units face a registration hold that prevents enrollment in future courses. Similar policies exist at universities nationwide to ensure students can complete their degrees within a reasonable timeframe.

If you’re further along—a junior or senior—changing majors becomes more complex. You may need dean approval, particularly if you’ve exceeded 135 units, and you’ll need to carefully evaluate whether you can complete new requirements without exceeding your institution’s unit ceiling (often 200 units). This doesn’t mean it’s impossible, but you should consult with advisors in your intended major to develop a realistic graduation plan.

The exact steps for changing your major vary by institution, but most follow a similar general process. First, you’ll need to research your intended major’s requirements, including any GPA minimums, prerequisite courses, or portfolio submissions. Some competitive majors (like nursing, engineering, or business) have limited capacity and require a formal application with no guarantee of acceptance.

Next, schedule a meeting with an academic advisor. Many universities recommend meeting with advisors in both your current and intended majors. Your current advisor can help evaluate your progress and discuss alternatives, while an advisor in your new major can confirm you meet eligibility requirements and explain the declaration process. At Ohio State, for example, some departments require students to complete an overview session before declaring.

Once you’ve confirmed eligibility, you’ll submit a formal request. This may be as simple as an online form through your student portal, or it may require written approval from department chairs and deans. At Texas A&M, students submit change-of-major requests through the Howdy portal but must first review department-specific requirements. Processing times vary from same-day to four to six weeks, depending on whether college-level approval is required.

Not all majors are equally accessible. Many universities designate certain programs as “competitive,” “selective,” or “restricted,” meaning admission isn’t guaranteed even if you meet minimum requirements. Engineering, nursing, business, computer science, and communications are commonly restricted due to high demand and limited faculty or facility capacity.

At Cal Poly San Luis Obispo, for example, students must complete an eligibility inquiry form and may need to develop an Individualized Change of Major Agreement (ICMA) with specific benchmarks. Some majors are entirely closed to internal transfers at certain times. At UC Berkeley, changing to a “high demand” major requires a comprehensive review rather than a simple GPA check.

If your desired major is competitive, approach your plan strategically. Complete all prerequisite courses with strong grades before applying. Build relationships with faculty in that department through office hours or research opportunities. Have backup options ready—consider related majors or minors that could still lead to your career goals. At many institutions, being denied entry to a competitive major doesn’t mean you can’t reapply after strengthening your academic record.

One of the biggest concerns students have about changing majors is losing financial aid. The good news: for federal aid like Pell Grants and Direct Loans, your specific major generally doesn’t affect eligibility. What matters is maintaining Satisfactory Academic Progress (SAP), which typically requires completing your degree within 150 percent of the published program length—so six years for a standard four-year degree.

Where you need to be cautious is with scholarships. If you received a department-specific or major-specific scholarship (such as a nursing scholarship or engineering award), changing your major may disqualify you from that funding. Contact the scholarship provider directly to understand their policies before making any changes. Some scholarships allow one major change; others terminate immediately upon switching fields.

Additionally, if changing your major extends your time in school, you could exhaust certain types of aid. Pell Grants, for example, have a 12-semester lifetime limit. If you’re already in your third or fourth year when you switch, calculate carefully whether you’ll have enough aid eligibility remaining to complete your new degree requirements.

If you haven’t declared a major yet or are considering returning to undeclared status, know that most universities have programs specifically designed to support exploratory students. At UC Davis, the College of Letters and Science encourages major exploration and provides an Academic Options Program with dedicated advising. Many students find that starting undeclared actually helps them make a more informed choice.

Undeclared programs typically give you until around 90 units (roughly the end of sophomore year) to declare. During this time, you should complete general education requirements that apply across multiple majors, take introductory courses in fields you’re considering, and utilize career counseling resources. Many universities offer courses specifically for undeclared students, such as career-planning seminars or major-exploration workshops.

The risk of staying undeclared too long is that you may delay completing prerequisites for your eventual major, potentially extending your graduation timeline. Balance exploration with progress by choosing general education courses strategically—select options that could count toward multiple majors you’re considering.

Before finalizing your decision, distinguish between productive and potentially problematic reasons to change. Productive reasons include: discovering a genuine passion for a new field, realizing your career goals have evolved, finding that your strengths align better with different coursework, or recognizing that your original choice was based on external pressure rather than personal interest.

Potentially problematic reasons include: struggling in one difficult course, disliking one professor, wanting to avoid challenging requirements, or believing another major will simply be “easier.” Difficult courses exist in every field, and running from challenge often just delays the inevitable.
Ask yourself these questions: Would you be excited to take upper-division courses in your new major? Can you see yourself working in careers associated with this field? Have you talked to students currently in the program about their experience? Have you explored internships or job descriptions in the related field?

If you’ve done thorough research and your answers point toward change, trust yourself. Research from institutions like EAB has shown that students who change majors actually graduate at higher rates than those who don’t—particularly when they switch early and intentionally.
