National 5 Physics: the free resources, and how the exam actually works
19 July 2026
National 5 Physics covers mechanics, electricity, and waves and radiation, and asks for genuine formula selection and unit-consistent calculation alongside conceptual understanding, not just memorised definitions.
- Qualifications Scotland's own past papers and marking instructions: free, no account needed, the only place to see exactly how a real answer is marked.
- Isaac Science (formerly Isaac Physics): free, built by the University of Cambridge and funded by the Department for Education, thousands of genuinely free physics problems from GCSE level upward, with hints, not just answers.
- IOPSpark, the Institute of Physics's own free resource hub: free, from physics's own professional body, not a commercial publisher.
- PhET Interactive Simulations: free, University of Colorado Boulder, genuinely useful for visualising circuits, waves and forces.
- Khan Academy: free, non-profit, solid extra practice on the underlying maths a physics calculation needs.
How National 5 Physics is actually assessed, in plain terms: a written question paper alongside an assessed practical component, both contributing to the final grade (A to D). Exact paper structure and how the practical is assessed are set by Qualifications Scotland (which replaced the SQA as Scotland's national awarding body in February 2026), so the National 5 Physics course page on its own site has the current, definitive version.
How markers actually award marks matters a lot in physics specifically: correct working and correct formula selection can earn marks even with a small arithmetic slip at the end, but only if the working and units are actually shown.
Our own Ziggy's Den has free-to-try National 5 Physics lessons and quizzes if you want some structure alongside the tools above.
Free tools explain the theory well, but they can't watch your learner's own working and catch exactly where a formula or a unit went wrong. If that's the gap, browse our National 5 Physics tutors directly.
General guidance, not professional or legal advice, for anything that matters for your specific situation (exam-board deadlines, your local authority's requirements, ASN entitlements), confirm directly with the relevant official body.
