The Cross-College Challenge (XCC) is the BU Hub’s signature project-based, 4-credit elective course open to juniors and seniors from all of BU’s undergraduate schools and colleges. XCC provides a unique opportunity for faculty, staff, and community partners to explore a complex real-world problem or an enduring human question with an interdisciplinary team of undergraduate students.


“When you get a group together that’s coming from all these different backgrounds, you avoid groupthink. So your ideas are more innovative, more creative.

Emily de Redon, Questrom graduate teaching assistant
