Attendance Calculator
Track your class attendance, see how many classes you can safely skip, or get a recovery plan if you're falling behind the required threshold.
📊 Attendance Parameters
Number of sessions you have physically attended.
Total classes held so far (including any missed).
This is the minimum percentage required by your institution (e.g., 75% or 80%). If your attendance falls below this, you may be barred from exams or face penalties.

📚 Understanding Attendance Compliance
Most universities enforce a minimum attendance requirement (often 75% or 80%) to allow students to sit for final exams. Falling below can lead to debarment (being barred from exams), grade penalties, or loss of financial aid.

🧮 Calculation Formulas
- Attendance % = (Attended ÷ Total) × 100
- Safe miss count = floor( (Attended – (Threshold% × Total)) / Threshold% )
- Recovery needed = ceil( ((Threshold% × Total) – Attended) / (1 – Threshold%) )
🧠 Smart Attendance Strategies
- Use a calendar to mark all lecture dates at the start of the semester.
- Set reminders for high‑weight classes where attendance is mandatory.
- If you must miss a class, inform your professor and borrow notes.
- Check your attendance every 2–3 weeks – early correction is easier.
📊 Example Walkthrough
Attended = 30, Total = 45, Threshold = 75% → Current % = 66.7% (below). Recovery needed = ceil( (0.75×45 – 30) / (1–0.75) ) = ceil( (33.75–30)/0.25 ) = ceil(3.75/0.25) = ceil(15) = 15 consecutive classes.
