Exams
Timed exams on a real machine, graded on what you actually did. You decide how you're graded — task by task, or all at the end.
Check as you go
Finish a task, press Check, and see exactly which requirements pass. Fix it and check again — then move on with confidence.
Graded at the end
The real-exam rehearsal: no feedback until you submit. Then a full report with partial credit, weak skills and every solution.
Level exams
Milestones that prove a level. Pass one and you get a BrokenCluster certificate to share.
Mock exams
Realistic, timed practice on one shared machine. New tasks and values on every attempt.
