Method and background
How this is calculated
Current attendance is what you have over what was held. The number that matters is forward-looking: apply the requirement to the full term including classes not yet held, subtract what you have already attended, and that is the minimum you must still attend. Anything beyond that is your remaining budget for missing, which is the question everyone is actually asking.
the classes still needed are the requirement applied to the whole term, less what you have- A
- Attended so far
- H
- Held so far
- R
- Remaining
- r
- Required fraction

Frequently asked questions
- How many classes can I miss?
- That is the figure on this page. It works forward from the whole term rather than backwards from today, which is why it differs from a simple percentage of the classes remaining.
