Fail grade

An essential Moodle quiz access rule plugin designed to enforce mastery-based learning. This plugin prevents students from starting new quiz attempts once they have proven their competency, encouraging them to focus on other areas once mastery is achieved. Key Features: Dual-Mode Mastery Locking: Lock extra attempts based on passing grade or mapped competencies. Custom Per-Quiz Competency Threshold: Configure custom passing percentage per quiz (or rely on global threshold). Real-Time Competency Progress Table: Displays interactive competency progress bars on the quiz page. Moodle Event Logging: Fires security audit events when attempts are blocked. Privacy & Backup: Full GDPR compliance and core backup/restore support. Credits & Acknowledgments: Based on original work by Alexandre Paes Rigão Licensed under GNU GPL v3 or later.
