One loop: practise, review, improve, reflect.

1. Simulation: real practice

Students answer exam-style questions under timed conditions, the way they will meet them on the day. Each question is split into three steps of the DDE Model, so the student commits to each step in turn:

• Discovery: work out one fact the question doesn't state directly.
• Declaration: name the equation, rule or relationship that applies.
• Execution: carry it through to the answer.

2. Review: know your gaps

After the test, every mistake is walked through step by step. Because answers are recorded per step, the review shows whether the problem was understanding the question, choosing the method, or the working itself. Multiple-choice options are written around real, named mistakes, so a wrong choice tells you which misconception is behind it.

3. Improved: score goes up

The next Simulation targets what Review found. Students repeat Simulation and Review until the topic clicks.

4. Reflection: make it stick

Students describe in their own words what they now know. Explaining a method is a stronger test of understanding than choosing an answer, and it is what makes the learning last.
