Edexcel modular IGCSE Physics lets students sit unit exams when ready (from May/June 2025 first assessment cohorts), resit individual units, then cash-in for a final grade — instead of only the linear 4PH1 two-paper end-of-course model.

Modular physics revision priorities

• Formulae and units — formulae given vs memorised
• Show working on every calculation question
• Definitions — precise wording for waves, electricity, energy
• Unit-by-unit syllabus — mechanics vs electricity may split across units; check Pearson spec
• Past papers: 4PH1 Edexcel past papers for style; modular samples from Pearson for exact layout

Resits and timing

If Unit 1 goes badly, you may resit that unit in a later June/November series before cash-in — discuss deadlines with your exams officer (school policies vary).

Frequently asked questions

Is modular physics international only?

Yes — UK schools use linear IGCSE/GCSE routes.

Same difficulty as 4PH1 linear?

Pearson aligns content standard; preparation is equally demanding.

Modular maths same board?

Maths modular IGCSE Edexcel — clearest worked example of unit codes.

Combined Science modular?

Double Award also has a modular route from 2025 — ask your school if you sit combined vs separate sciences.
