Frequently asked questions
How is attendance percentage calculated?
Divide attended classes by total completed classes and multiply by 100.
How many absences can I have?
It depends on the required minimum, accumulated absences and remaining classes. The calculator estimates additional absences allowed without falling below the final minimum.
What happens if I am below the minimum?
The calculator checks whether you can recover with remaining classes and shows how many you would need to attend.
Can I include remaining classes?
Yes. Enter the classes remaining in the course to estimate the final scenario, not only the current percentage.
What does it mean when the minimum can no longer be reached?
It means that even if you attend every entered remaining class, the final percentage would remain below the requirement.
Do excused absences count toward the percentage?
It depends on your school's rules. In this calculator, all entered absences count equally toward the percentage.
