H2 Physics Paper 4 Technique File: What to Keep From Every Practical
A H2 Physics 9478 Paper 4 technique-file guide for turning lab worksheets into reusable notes on measurement, graphs, uncertainty, planning, and apparatus.
The core idea is simple: A technique file turns each practical into reusable exam habits.
Use it as a working check: Keep setup, measurement, graph, uncertainty, planning, and ACE notes for every investigation.
Then go one layer deeper: After each lab, write the fault you met, the fix that worked, and the sentence you would use in Paper 4.
H2 Physics Paper 4 is not revised well by rereading old worksheets. The useful version is a technique file: a small set of notes that records what the apparatus did, how the data was processed, and how you would write the answer under exam timing.
Use the H2 Physics practical lab mastery guide for the full Paper 4 map. Use this page to build the file you keep beside every practical.
The five-page technique file
| Page | What to keep | Why it matters |
| Apparatus families | Circuit, mechanics, waves, thermal, field, and sensor setups | Paper 4 often tests recovery when a setup is unfamiliar |
| Measurement habits | Zero error, repeats, range, resolution, and alignment | MMO marks depend on controlled measurement |
| Graph and spreadsheet routes | Axis choice, linearisation, gradient, intercept, residuals |
