How this calculator works
If your attendance is below target, the calculator solves:
(Attended + x) / (Held + x) ≥ Target.
If you are already above target, it calculates how many future classes can be missed while staying at or above the target.
Example
If 100 classes were held and you attended 70, you need to attend 20 consecutive classes to reach 75%.
Frequently asked questions
Can I use a target other than 75%?

What does consecutive classes mean?
It means the next classes must all be attended until the target is reached.
If I am already above 75%, can it tell me how many classes I may miss?
Yes. It estimates how many future classes may be missed while keeping attendance at or above the target.
