About this tool
Track practical and lab attendance separately from theory, weight lab sessions by contact hours and see the experiments still pending.
This tracker scores practical attendance as its own head of account rather than folding it into the theory average, because that is how universities detain students. It computes the lab percentage as sessions attended ÷ sessions held × 100, tests it against a separate bar (usually 75%), and reports the combined figure two ways — counting sessions and counting contact hours, since a two-period lab slot is marked as two hours on the roll. Pending experiments are tracked alongside, because a complete record book is a second, independent condition for a practical course.

Puts unsigned experiments next to the percentages as a separate blocker.
Yes. A practical course carries its own course code, its own roll and its own attendance percentage, so a student can clear the theory bar and still be detained in the lab. Check the practical figure on its own line in the portal rather than reading only the overall average.
Either by counting sessions — (theory attended + labs attended) ÷ (theory held + labs held) — or by weighting each entry by its contact hours, which is what most timetable-driven portals do. A student at 32 of 40 lectures and 8 of 12 two-hour labs is 76.9% by session count but exactly 75.0% by contact hours, because the missed labs carry double weight.
At a 75% bar, one missed session in four is the ceiling, but labs run weekly rather than daily, so a semester may hold only 12 to 15 sessions in total — three absences out of 12 already puts you at exactly 75% with no margin left. This is why a lab shortfall is far harder to recover than a lecture shortfall.
Most institutions treat the completed and signed record, along with the prescribed list of experiments, as a condition for the practical examination that is separate from attendance. Sessions attended without the write-up submitted usually do not count as the experiment being performed. Ask your lab in-charge about a repeat or make-up slot while the semester is still running.
