Frequently asked questions
How is attendance worked out?
Classes attended divided by classes held, times 100. For example 32 out of 40 is 80%.
How does it know how many classes I can miss?
It checks, class by class, how far your percentage can fall before it goes under the limit. The answer assumes the classes you miss are still held.
My college counts medical leave or rounds the percentage. What then?
Colleges have their own rules about condonation, medical leave and rounding. Use this as a guide and follow your own college's rules for the final decision.
Is my data saved?
