How do graduate students and undergraduates interact?
In some cases, graduate students take some of the same classes as undergraduates, or act as teaching assistants for some courses, and a few serve as residence assistants in the undergraduate houses. Due to the many research opportunities available, many undergraduates find themselves working alongside graduate students in labs and collaborating with them on research projects. Caltech is an intimate community where clubs and extracurricular activities are open to all, so graduates and undergraduates may play soccer together, sing in the same choral group, or tutor together in local schools.
