Simulate safe skips and recovery targets with deterministic mathematical formulas.
Deterministic Dual-Formula Engine
Skeddo evaluates attendance requirements using two exact mathematical formulas:
- Safe Miss (calculateCanMiss): When your current attendance is at or above your target, calculates how many classes you can miss consecutively before falling below your target percentage:
floor((present - target * conducted) / target). - Required Attendance (calculateMustAttend): When your attendance is below target, calculates the minimum consecutive classes you must attend without missing to restore your standing:
ceil((target * conducted - present) / (1 - target)).
Important Disclaimer
Results are estimates based on the numbers you enter. Your institution's attendance rules, subject requirements, and scheduled classes may differ.
