Which is better for major flexibility: Northwestern or UC Berkeley?

The biggest practical tradeoff is this: Northwestern usually gives you more day-to-day flexibility to explore and switch directions across schools and departments, while UC Berkeley offers huge academic breadth but can make some major changes harder because certain colleges and high-demand majors are more structured or capacity-limited. If you are undecided, that difference matters a lot. At Northwestern, students often have more room to move around before locking in a path, and advising is typically built around that kind of exploration.

Northwestern is especially friendly to students who want to combine fields or pivot later. It is well known for relatively easy access to courses across disciplines, and programs like double majors, minors, and cross-school study are a normal part of the academic culture. Internal transfer processes do exist, but the university’s quarter system and smaller undergraduate environment usually make experimenting with different subjects feel more manageable.

Berkeley absolutely has more than enough classes and departments to explore, but flexibility can depend heavily on where you start and where you want to go. Some majors are capped, selective, or require prerequisite performance before you can declare, and moving between colleges can be more complicated than simply changing your mind.

For pure major flexibility, I would give the edge to Northwestern. Berkeley gives you enormous academic range, but Northwestern is more likely to let an unsure student explore broadly without running into as many administrative or capacity barriers later.
