Mudders tend to do very well in applications to grad school. Some have slightly lower GPAs, but they usually have excellent research experience, strong recommendations, and do well on the STEM GRE tests that many grad school programs require (like Physics GRE, for example). Mudd is really committed to giving students research experience early on, too - many freshman research on campus summer after freshman year. My kid was a CS major for a while before switching to Physics, and she did CS research summers after freshman & sophomore years. Mudd is second only to Caltech overall in colleges sending students to PhD programs:
