Attendance Calculator
Calculate required classes to meet your target attendance threshold.
How It Works
Current Attendance Percentage = (Attended / Total) * 100.
If your percentage is below target, the calculator finds the minimum additional consecutive classes you must attend: Math.ceil((Target * Total - 100 * Attended) / (100 - Target)).
If your percentage exceeds target, it computes how many upcoming classes you can safely miss without dropping below your goal: Math.floor((100 * Attended - Target * Total) / Target).
