Show the practical. Share the link.
Put a required practical on the board, send pupils to it with one link, and print the teacher and technician pack. Pupils then answer exam questions on their own results.
No account for you or your pupils. Nothing about a pupil is collected.

Where it fits in a practical lesson
Your lesson is unchanged. The Lab goes either side of it.
- Before: they preparePupils open the practical on their own device, meet the apparatus, make a prediction and answer the checkpoint questions.
- During: the real practicalThey already know the order of the method, the hazards and where the errors come from, so the time goes on doing and observing.
- After: the exam questionsPupils answer on their own readings and mark each one against the mark scheme, point by point. Nothing extra for you to mark.

What is not built yet
We would rather you heard it here than found it out in a lesson.
- Class results. Nothing about a pupil comes back to you or to us; a pupil’s work stays on their own device.
- Review by a subject specialist or an exam board. There is none: questions are checked automatically and marked as draft or auto-checked. How content is checked.
- A replacement for the real practical. The readings are simulated; it is for rehearsal and for practising the questions.
It is free for teachers and pupils, with no licence to buy. We collect no pupil data. The public fix log shows what changed. More in questions and answers and exam practice.
