Attendance Calculator — frequently asked questions
How is attendance percentage calculated?
Attendance % = classes attended ÷ total classes held × 100. The tool also shows how many classes you can still miss, or must attend, to reach your required percentage. Example: 66 of 80 classes is 82.50%, so with a 75% requirement you can still miss 8 more; 50 of 80 is 62.50%, and you would have to attend the next 40 classes in a row.
What is the 75% attendance rule?
Many colleges require 75% attendance to sit exams. Enter your college's required percentage and the tool does the maths.
