SL course

Physics SL

Motion, forces, energy, waves, fields, nuclear physics, and practical-data reasoning with calculation and diagram practice.

Guided practice pathways

Assessment routes built from the live skills in this course. Each pathway moves from the first decision students need to make toward the kind of source use, calculation, writing, or judgement that costs marks in real assessment.
