HL course

Physics HL

Physics HL practice for multi-step mechanics, fields, waves, energy, quantum and nuclear ideas, and experimental judgement.

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.
