Purdue vs Brown for science: which is better for undergraduate science majors?

Brown has the edge for most undergraduate science majors if you want a more flexible academic experience, smaller class settings sooner, and easier access to faculty across departments. Its Open Curriculum lets science students shape their schedule without a long list of core requirements, and that can make it easier to combine biology, chemistry, physics, math, or even non-STEM interests in a deliberate way.

Research access is strong at both schools, but it tends to feel different. At Brown, the undergraduate population is smaller and the culture is very centered on undergrads, which can make it more straightforward to find lab roles, pursue independent study, or build close mentoring relationships.

Teaching style is another real distinction. Brown science courses are often discussed as more discussion-friendly and less rigidly structured, which works well for students who like intellectual exploration and asking big questions across fields. Purdue is excellent in STEM and has serious scientific infrastructure, but introductory science classes can be larger and the environment can feel more utilitarian, especially in the early years.

Support in science classes depends on what kind of support you want. Brown tends to serve students who benefit from advising flexibility, cross-disciplinary freedom, and a collaborative atmosphere. Purdue is especially compelling for students who want a large public university with broad STEM depth, many specialized labs, and a more structured path through science coursework.
