For grading at real scale — a full cohort's worth of open-text answers on one milestone — the review screen has a few tools worth knowing beyond grading one submission at a time.
The CSV Round-Trip
Download every submission for a milestone as a CSV, grade and comment on them offline in whatever spreadsheet tool you prefer, then re-upload the file to apply everything at once. Much faster than clicking through submissions one by one when you've got dozens or hundreds to get through.
Pending Validation Reminders
Export a CSV of exactly which players still have ungraded submissions waiting — built specifically to feed into an email campaign nudging graders (or players) about what's outstanding.
Grading Scale
Depending on what you set in Resource Mechanics, you'll grade on a straight percentage or on letter grades (A through F). Whichever you choose, it's applied consistently across the review screen.
Manual "Validate with A.I."
Even on a milestone with AI grading already enabled, you can trigger a manual AI validation on any individual submission as a spot-check — separate from the automatic validation that ran when the player submitted it. Useful for a second opinion on a borderline case before you commit to a grade.
