Which is better for smaller class sizes, Purdue or Bucknell?

Bucknell is better for smaller class sizes and a more personal undergraduate classroom experience. It is a much smaller university overall, and that usually shows up in day-to-day academics through more seminar-style courses, more direct access to professors, and fewer very large introductory lectures. Purdue, by contrast, is a major public research university, so large first-year classes are much more common, especially in high-demand fields like engineering, business, and the sciences.

At Bucknell, undergraduates make up the center of the academic experience, so even intro courses are more likely to feel discussion-based or professor-led rather than built around a huge lecture format. You are also more likely to see faculty, not graduate teaching assistants, handling a larger share of teaching and advising. That tends to matter if you want classes where professors know your name early on.

At Purdue, the experience depends a lot on major. In some departments, especially STEM, it is normal to have large lecture classes at the start, with smaller recitation, lab, or discussion sections attached. So you may still get some small-group interaction, but the core class itself is often bigger and less personal than what Bucknell typically offers.

The classroom culture is different too. Bucknell’s smaller scale usually makes it easier to build relationships across multiple classes with the same professors and classmates. Purdue offers many academic resources and opportunities, but for pure class-size experience, Bucknell is the one more likely to give you consistently small, undergraduate-focused classes.
