Frequently asked questions
How is attendance percentage calculated?
Divide the classes you attended by the total classes held and multiply by 100. Attending 32 of 40 classes is 32 ÷ 40 × 100 = 80%.
What does "classes you can still miss" mean?
If you are already above the required percentage, this is the number of consecutive classes you could skip before your attendance would drop to the requirement. Attending every remaining class would keep it higher.
Why is the default requirement 75%?
75% is a common college/school attendance minimum, but you can change it to any value from 1% to 100% to match your institution's rule.
