  • Force, work and energy
  • Light, sound and electricity
  • Earth and atmosphere

How to prepare

Revise school-level concepts, connect each concept to a familiar example, then practise mixed questions. When an answer is wrong, write a one-sentence explanation of the governing principle before trying a similar item.
