Every topic, in every subject, works the same way: change one thing, watch what happens, then learn the words that get the marks.

  1. 01 / Understand

    Get the idea.

    The idea in plain words, with the exam definition next to it.

  2. 02 / Experiment

    Change one thing.

    A small lab: move a slider, flip a switch, read what just happened.

  3. 03 / Interpret

    Write it for marks.

    The cause → effect chains to remember, and one exam tip.
