An exam room, not a quiz page

Timed, sectioned exams with the tools of the official room, in a Bluebook-emulated interface or Crucible’s own.

Run a proctored sitting in the room, or send practice links for students to take anytime. Crucible only takes away the printing, the bubbling, and the grading.

Section timer: A section countdown with a 5-minute warning.
Mark for review: Flag a question and come back.
Answer eliminator: Cross out choices to narrow the field.
Question grid: Answered and flagged at a glance, jump anywhere.
Gated sections: A closed section cannot be reopened, as on the real exam.
Autosave: Answers survive a dropped connection; students resume mid-section.

02The live console

Every seat, watched

Who is in progress, who has gone quiet, who rushed the finish, every 15 seconds. The proctor extends time, stops a test, or revokes a link for a retake.

Not a camera

No video, no screen recording. Crucible reads presence and pace, flags what looks off, and leaves the room to the proctor.

Scored in seconds

Scoring runs the moment a test comes in, before the room empties.

Seating

No student accounts, just a link per seat

No installs, nothing to set up: staff assign the test and each student receives a secure link bound to the exam window, revocable and reissuable on the spot.

Analytics

Analytics on every question and every student

For each student, strengths by category, pacing, and every answer on record. For each question, how hard it was, how well it separated strong scorers from weak, and which wrong answers attracted them. When the key itself is wrong, Crucible says so.

19 of 24 students chose B while the key says D. Crucible flags the key, not the students.
