    Putnam Prep FAQ

    What is this?

    A complete training system for the Putnam competition: a 28-week gated curriculum with exact sources, a 4,272-problem archive with answer checking, spaced repetition, mock exams in the real format, and proof-grading tools.

    Why gates instead of a syllabus?

    Every week is a set of gates — load, drill, bridge, reflect, verify. A gate names its exact source and problem range. A library is not a curriculum; the gate architecture makes skipping visible.

    Is the content validated?

    Yes, mechanically. The curriculum lives as data, checked at every build: schema shape, prerequisite ordering, retention gaps, and every archive reference must resolve. A bad edit fails the build before it ships.

    Who is this for?

    Built by one student training for Putnam 2026 in public. The system generalizes to anyone who wants top-quartile problem-solving on a real calendar.
