FAQs
How is attendance percentage calculated?
Attended classes are divided by the total classes held and multiplied by 100. For example, 32 out of 40 classes is an 80% attendance rate.
What if I enter more attended classes than were held?
That cannot happen in practice, so the calculator caps attended classes at the total held. Double-check your numbers if the result looks unexpected.
How is the number of classes I can miss worked out?
It finds the largest number of extra absences that keeps your rate at or above the target, assuming you attend every other class from now on.
Is my data sent anywhere?
No. The calculation runs entirely in your browser and never transmits or saves your entries.
