* The new major's requirements: The new major may require specific courses that you haven't taken yet. Credits earned in courses that fulfill general education requirements or elective requirements in your previous major *might* still count toward your new major, but it's not guaranteed.
* The similarity between the majors: If the two majors are closely related (e.g., Biology to Biochemistry), a higher percentage of your credits will likely transfer. If they are very different (e.g., Engineering to English Literature), fewer credits might transfer.
* Your college's policies: Each college and university has its own policies regarding transferring credits between majors. Some institutions are more flexible than others. It's crucial to check with your academic advisor in the new department *before* officially changing your major.
* Course content: Even if a course seems relevant, its specific content might not align with the new major's requirements. The college may evaluate the syllabus to determine if credit can be awarded.
In short, you should expect *some* credits to transfer, but not necessarily all of them. Meeting with an academic advisor in your intended new major is the best way to determine how many credits will transfer and plan your course schedule accordingly.
