Are these aligned to the lower-sec IP Combined Science syllabus?

Yes - they cover the Sec 1–2 IP pathway across measurement, matter, cells, systems, forces, energy, waves, and electricity.

Do you include worked examples and lab-skill reminders?

Each chapter includes worked examples, common pitfalls, and lab/graphing reminders to build good habits early.

Can I download everything as one PDF?

Yes - download /pdf/IP-Combined-Science-Lower-Sec-Notes-Complete.pdf for the consolidated printable bundle.

How should I pace revision across Y1 and Y2 topics?

Use the outline to secure measurement/matter first, then cells/systems, followed by forces/energy and waves/electricity as you approach exams.

Are these notes free?

Yes. If you want a tailored plan for your next test, WhatsApp us and we'll point you to the exact chapters and drills.
