Check your attendance percentage, find out how many classes you must attend to reach your target (like 75%), and how many classes you can safely miss.
Attendance % = (classes attended ÷ total classes held) × 100. Example: attending 45 of 60 classes gives 45 ÷ 60 × 100 = 75%.
Classes needed to reach a target: if you attend every coming class, the number needed is (target × total − attended) ÷ (1 − target). This tool does that maths for you and rounds up, because part of a class does not exist.
Classes you can miss: the largest number of future classes you can skip while staying at or above target — assuming the total keeps growing by the classes you miss.
Many colleges require 75% (sometimes 65% or 80%) to sit in exams. The exact rule is your institution's — this calculator helps you plan how to get back above your target.
Enter your totals above. Example: with 40 attended out of 60 (66.67%), you must attend the next 20 classes in a row to reach exactly 75%.
Yes. It is the number of classes you can skip from now on while all other classes are attended, staying at or above your target.
