The hardest thing on Mathagram. Beat this and you've truly mastered the site.
180 brutal questions across 12 cross-subject gauntlets — calculus monsters, abstract algebra, IMO geometry, Putnam problems, NP-hard algorithms, competitive-programming traps, knights-and-knaves logic, dead-language translation, memory marathons, mental-math under fire, ultra-fast typing — finishing with a no-help, no-skip Final Boss synthesis problem that pulls from every Mathagram course.
