01Subjects

Four subjects. One way of learning.

Each subject follows its own Cambridge syllabus, topic by topic. Start with what you need for the next test.

02How a topic works

Read less. Try more.

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

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

  2. 02

    Experiment

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

  3. 03

    Interpret

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

  4. 04

    Flashcards

    Key facts, then the harder Explain it cards. Your last score is kept.

Open the Electrolysis lab
Fig. 1 Try one: particles in a box Sweeping

What just happened Hotter particles move faster, so more of their collisions carry enough energy to react: the rings mark those hard hits.

Stay addicted.
Keep adding.

Your first topic takes five minutes. Every lesson you open lights up its tile, so the table fills in as you go.
