papertree AI lab for practical physics Join the waitlist

Cambridge International AS & A Level Physics 9702

Don’t just watch the experiment. Do it.

Use real-feeling virtual apparatus, make your own measurements and practise the decisions that Paper 3 actually tests.

Launch the springs lab See how it works

No sign-up required for the demo.

Interactive virtual apparatus with two spring oscillators.

One practice loop

Your method matters as much as your answer.

  1. 01 Set up and measure

    Change masses, release the system and collect your own readings.

  2. 02 Complete the working

    Record data and reason through an exam-shaped practical task.

  3. 03 Review the process

    AI Observer is designed to explain technique and strategy, not just mark a number.
