How an active license is counted

An active license is a distinct student account, covered by a CodeChum license, that actually submitted work in that month:

  1. 1

    Usage that month only

    The student submitted at least one answer in the calendar month (UTC). Nothing carries over from earlier months.

  2. 2

    Institutional license

    The student's campus had an institutional license live during the month → every submitting student there counts.

  3. 3

    Individual license

    Otherwise, the student paid (per account or per class) under an individual license live that month.

  4. 4

    Pilots & partners

    Special licenses (pilots / partners) count like any other and are tallied separately by campus.

  5. 5

    Each person once

    One count per student account, even across several classes or both license types.

  6. 6

    No dummies

    Accounts on @codechum.com / @gradechum.com and test names (test, dummy, sample, demo, fake, qa, “Student 1”…) are excluded.
