- It assumes future classes are held consecutively without cancellation.

Logic Used
| Mode | Logic |
|---|---|
| Current % | (Attended / Total) × 100 |
| Classes Needed | Solves for X: (Attended + X) / (Total + X) = Target% |
| Can Skip | Solves for X: Attended / (Total + X) = Target% |
Practical Scenarios
Scenario 1: Shortage
Status: 30/50 classes attended (60%). Need 75%.
Result:
You need to attend the next 30 classes in a row without missing any.
Scenario 2: Safe Zone
Status: 45/50 classes attended (90%). Need 75%.
Result:
You can safely skip the next 10 classes and still remain above 75%.
FAQ
We mathematically calculate how many consecutive future classes you must attend (adding to both your 'Attended' count and 'Total' count) to raise your average to the desired percentage.
Yes! Use the "Subject-wise" tab. You can add as many subjects as you like, and the tool will calculate the aggregate percentage for all of them combined.
No problem. In the "Student Information" section at the top, you can change the "Minimum Requirement" field from 75 to 85 (or any number).
