How it works

Current attendance is attended ÷ held, while target sessions round required percentage × full-term sessions upward. Missable future sessions equal attended plus every remaining opportunity minus that minimum, clamped at zero.

Formula
minimum attended sessions = ceiling(required percentage × total sessions)
  • Eighty percent is an editable example, not an institutional policy.
  • Every session has equal weight; hours, excused absence, partial credit, and policy-specific rounding are absent.

Worked example

A course with sessions left to run
Input
											Sessions held: 20
Sessions attended: 17
Sessions remaining: 10
Required percent: 80
Output
												Current percent: 85
Total sessions in term: 30
Minimum attended needed: 24
Sessions can still miss: 3
On track: yes

When to use this

Courses convert handbook thresholds, students check whether recovery remains possible, and training programmes compare equally weighted sessions.

Edge cases

  • 17 of 20 attended with 10 remaining and an 80% target allows three further misses because 24 of 30 are required.
  • Attended sessions cannot exceed sessions already held.
  • When even perfect future attendance cannot reach the target, missable sessions stay zero and on-track is false.
