"One deck. Entire semester. I started with just Root cards for shoulder anatomy. By midterms, I was doing Branch-level clinical questions. Same deck, just filtered differently."
Dr. Chen
Palmer '19, Creator
"I organized my 800-card anatomy course into Root-to-Leaf in one weekend. Students love starting simple and choosing when to go deeper. Made $8,400 in 4 months."
Marcus T.
Life '24, Graduate
"Started with Root in January. Unlocked Branch by March. Crushed Part 1 in June with 89%. The layered structure made neuroanatomy actually make sense."
