Bennington in Vermont also has narrative reports, thought a student can also request grades if he or she is concerned about grad school.
Lecture classes break into “sections” for discussion or small group work, often with grad students as teaching assistants leading them.
You never know- I took English classes as an adult at UMass Boston and the classes were quite small, and directly taught by the professor, with lots of discussion.
I agree it depends on the department size: smaller departments will have fewer large lectures, obviously, but a personalized experience is possible in CS or science.
One thing to look into: many students who have done AP’s or dual enrollment still select to do intro courses in CS or science once on campus, because the foundational sequence may be different at the new school.
