How to use this guide
Level and subject labels indicate a plausible teaching fit, not a prescribed placement. Check your current DSKP, scheme of work, learner readiness and available class time before assigning a lesson.
KSSR/KSSM labels describe the national curriculum. Private and international schools should use the scientific topic and activity demand to map lessons to their own curriculum.
Lessons open in English. Keep official Malay terms such as Tahap II and Reka Bentuk dan Teknologi (RBT) in view where they help colleagues recognise the curriculum route.
