📖 Controls Reference
All 110 CMMC Level 2 controls organized by 14 domains. Filter by study status, implementation type (Policy, Config, Software, Hardware, Mixed), and search across all controls. Progress tracked locally.
✏️ Quiz Mode
Multiple choice, flashcards, type match, and domain match. Configurable question count with smart wrong-answer boosting — questions you miss appear more frequently until you get them right consistently.
⚖️ Professional Conduct (36 questions)
CoPC principles (POCMI), conflict of interest scenarios, cooling-off periods, consulting prohibitions, role boundaries (CCP vs CCA vs CCI), and real-world ethics situations that test how assessors are expected to behave before, during, and after an engagement.
⚡ Watch Out (16 questions)
The rules, distinctions, and edge cases that trip up even experienced assessors — POA&M restrictions, partial scoring logic, asset categorization traps, evidence terminology, and regulatory gotchas.
🎯 Assessor Judgment (84 scenarios)
Real-world assessment situations requiring applied reasoning: evidence evaluation, adequate vs. sufficient calls, scoping decisions, SSP accuracy gaps, inheritance verification, artifact matching, partial implementation scoring, and the EXAMINE/INTERVIEW/TEST method selection.
📋 CAP Process (46 questions)
All four CAP phases, roles (Lead CCA, QA Individual, Affirming Official, Authorized Certifying Official), mandatory vs. optional documents, in-brief and out-brief requirements, POA&M closeout rules, and CONDITIONAL vs. FINAL certification paths.

Asset categorization under pressure — CUI Assets, Security Protection Assets (SPA), Contractor Risk Managed Assets (CRMA), Specialized Assets (IoT, OT, GFE), and Out of Scope.
