Questions
How many classes can I skip at 75%?
Enter the classes you have attended and the total held so far. The calculator finds the largest number of upcoming classes you can miss while staying at or above 75%.
How is the number of classes to attend calculated?
If you are below the target, you need x more classes so that (attended + x) ÷ (total + x) ≥ target. Solving gives x = (target × total − attended) ÷ (1 − target), rounded up.
