Did I use my time well?

Time per subject — Maths 61 min, Physics 55 min, Chemistry 51 min — and how it split: 125 min on right answers, 30 min on wrong answers, 11 min on questions finally left blank. Then how many answers came in each half hour: a steady 5–12 right answers in every half hour, through to submitting at 171 minutes.

Time is the quiet lever. Eleven minutes went on questions that earned nothing; the half-hour bars show whether you kept a steady pace.

Shows whether the paper was rushed or used well. This sample used almost the full three hours at an even pace — a good habit.

A pacing profile per student: half-hour buckets show when answers were given; the right / wrong / blank split shows where the minutes paid off.
