Which has stronger undergraduate teaching, Boston College or Brown?

The biggest practical difference is structure: Boston College builds undergraduate learning around a substantial Jesuit liberal-arts Core Curriculum and close faculty advising, while Brown gives students far more control through its Open Curriculum. At BC, that structure can produce a more consistently supported classroom experience, especially for students who value discussion-based courses, clear academic expectations, and regular guidance. At Brown, the quality of instruction is excellent, but students take greater responsibility for constructing a coherent program and seeking out relationships with professors.

Brown offers unusually engaging classes for students who are curious and proactive. Its Open Curriculum lets a student pursue interests deeply without a long list of general-education requirements, and many faculty members welcome undergraduates into research, independent study, and seminar-style work. However, Brown also has large introductory courses in popular fields, and the freedom that attracts many students can feel less supportive to someone who wants built-in direction.

For the specific priorities you named, Boston College has a slight edge in consistent undergraduate teaching, professor accessibility, and classroom support. Brown may provide the more exciting academic experience for a highly self-directed student who wants to shape nearly every part of their education, but BC is more likely to deliver the dependable, guided teaching environment you describe.
