Frequently asked questions
How do I calculate my attendance percentage?
To calculate your attendance percentage, simply divide the number of classes you've attended by the total number of classes held, and then multiply by 100. Our attendance calculator does this automatically for you.
What happens if I miss more classes than allowed for 75% attendance?
If you miss more classes than allowed for 75% attendance, you might not be eligible to sit for your exams. It's crucial to catch up on missed classes or speak with your professor or department about possible alternatives.
Can I use this calculator for any attendance percentage goal?
Yes, our attendance calculator allows you to set any attendance percentage goal. Simply enter your desired percentage, and the calculator will provide you with the number of classes you need to attend to reach that goal.
How does the calculator determine how many classes I can safely miss?
The calculator uses the formula: Classes needed = ⌈(target × held − 100 × attended) ÷ (100 − target)⌉. This formula calculates the number of classes you need to attend to reach your target percentage and then subtracts that from the total number of classes you can afford to miss while still meeting the attendance requirement.
