Rutgers math professor Alex Kontorovich called it amazing and shared his own paper-based variant built for a high-school-to-middle-school tutoring camp, drawing on Math Academy ideas like spaced repetition, retrieval practice, and interleaving. He is now adapting the model at the college level, where students who aced Calc 2 would serve as Learning Assistants delivering paper worksheets tailored to each Precalc student's needs.
