Should I apply undecided to Johns Hopkins University if I’m not sure about my major?

Yes, if you’re not sure yet, applying to Johns Hopkins without locking yourself into a specific major is a normal and reasonable approach. Hopkins admits students to the university, not into most majors at the undergraduate application stage, so you usually do not need to declare a major when you apply. You can explore different fields once you enroll, and many students don’t declare until later.

That said, Hopkins is very academically focused, so your application should still show clear intellectual interests even if they span more than one subject. The university has strong options in engineering, natural sciences, social sciences, and the humanities, and students can take courses across the Krieger School of Arts and Sciences and the Whiting School of Engineering. If you’re torn between fields, it’s fine to write about that curiosity as long as you show depth, not just uncertainty.

One important exception is if you are applying to a specific program with its own admission process or structure, such as Biomedical Engineering in the engineering school.
