Lesson Lockdown and Exam Controls

Control when a student can no longer interact with lesson widgets during a live or timed workflow.

Who this is for

Teachers using stricter control during tests, homework review, or live-session supervision.

What this page answers

What does lesson lockdown do?
When is a lesson locked automatically?
What do students see when interaction is restricted?

Automatic locking

The most common automatic trigger is time expiry. When the allowed time runs out, the student can no longer interact with the lesson widgets.

Teacher-controlled locking

Teachers can also restrict interaction for a specific student during a session when the lesson needs to pause, close, or switch into a more controlled mode.

Exam mode

Exam mode is stricter than a normal timed lesson. It is designed for assessment-style work where students should not see whether each answer is correct while the exam is still in progress.

When a lesson is in exam mode:

students see a start screen before entering the exam
answer feedback is hidden while they work
the timer can be shown in the exam banner and bottom bar
students use Submit exam when they are finished
when the exam is submitted or time expires, the lesson becomes read-only and results can be shown

Teachers do not turn exam mode on from the ordinary lesson settings switch. Exam lessons are created or managed through the Lesson Builder exam flow. The settings sheet shows whether a lesson is an exam module and which exam part it belongs to.

What students see

Students keep their existing answers, but the lesson moves into a restricted state so they cannot keep changing the work.

Use this when consistency matters more than flexible retry behavior.

Defer answer reveal

For smaller checks, you can turn on Defer answer reveal without using a full exam module. Students can answer normally, but correctness colours, icons, and answer feedback stay hidden until they submit or the timer expires.

This is useful for:

short quizzes where students should finish all questions first
homework that should not reveal answers immediately
exam preparation where the full exam flow is not needed
