assessment structure
| Paper | What's assessed | Length | Marks | Weight | Question types |
|---|---|---|---|---|---|
| Paper 1 (J249/01, Foundation) | Topics P1-P4 and P9 | 1h 45m | 90 | 50% | Multiple-choice, short-answer, calculations, extended-response (including 6-mark essays) |
| Paper 2 (J249/02, Foundation) | Topics P5-P8 and P9 (with assumed knowledge of P1-P4) | 1h 45m | 90 | 50% | Multiple-choice, short-answer, calculations, extended-response (including 6-mark essays). Includes synoptic assessment |
| Paper 3 (J249/03, Higher) | Topics P1-P4 and P9 | 1h 45m | 90 | 50% | Multiple-choice, short-answer, calculations, extended-response (including 6-mark essays) |
| Paper 4 (J249/04, Higher) | Topics P5-P8 and P9 (with assumed knowledge of P1-P4) | 1h 45m | 90 | 50% | Multiple-choice, short-answer, calculations, extended-response (including 6-mark essays). Includes synoptic assessment |
Learners sit either the Foundation pair (Paper 1 + Paper 2) or the Higher pair (Paper 3 + Paper 4). OCR Gateway integrates 'global challenges' (P8) as a synoptic topic drawing on physics content applied to real-world contexts. Paper 2 and Paper 4 include additional synoptic assessment. Both papers in each tier assess practical skills (Topic P9, ~15% of marks) via OCR's 8 Practical Activity Groups (PAGs).
assessment objectives
| AO | What it means | Overall |
|---|---|---|
| AO1 | Demonstrate knowledge and understanding of scientific ideas, techniques and procedures. | 40% |
| AO2 | Apply knowledge and understanding of scientific ideas, techniques and procedures. | 40% |
| AO3 | Analyse information and ideas to interpret, evaluate, make judgements and draw conclusions, and develop and improve experimental procedures. | 20% |
required practicals
| Practical | What it involves |
|---|---|
| PAG P1 Materials | Use of appropriate apparatus to make and record measurements (length, area, mass, time, volume, temperature) and to determine densities of solid and liquid objects. |
| PAG P2 Forces | Use of appropriate apparatus to measure and observe the effects of forces, including the extension of springs. |
| PAG P3 Motion | Use of appropriate apparatus and techniques for measuring motion, including determination of speed and rate of change of speed (acceleration/deceleration). |
| PAG P4 Measuring waves | Making observations of waves in fluids and solids to identify suitable apparatus for measuring speed, frequency and wavelength. |
| PAG P5 Energy | Safe use of appropriate apparatus in a range of contexts to measure energy changes/transfers and associated values such as work done. |
| PAG P6 Circuit components | Use of appropriate apparatus to measure current, potential difference (voltage) and resistance, and to investigate the I-V characteristics of a range of circuit components. |
| PAG P7 Series and parallel circuits | Use of appropriate apparatus to construct and check series and parallel circuits using a range of components, including analysis of behaviour of energy, current and voltage. |
| PAG P8 Interactions of waves | Use of appropriate apparatus and techniques to investigate the interactions of waves, including reflection, refraction and absorption. |
higher vs foundation
| Aspect | Foundation tier | Higher tier |
|---|---|---|
| Grades available | 5-1 | 9-4 (with safety net grade 3) |
| Additional Higher content | Standard content | Adds: gas laws, momentum conservation, EM induction, transformers, more depth on P8 global challenges |
key tips for success
Learn Physics equations cold
Higher tier has reduced equation sheet. Learn: KE, GPE, work done, power, current/voltage/resistance, density, wave speed.
Master PAGs (Practical Activity Groups)
OCR uses PAGs to structure practical work. Learn method, expected results, sources of error for each PAG. Exam questions worth ~15% of marks.
Practise 6-mark essays
Both papers have 6-mark essays. Reward: clear points, developed explanation, evaluation. Practise the structure.
Learn P8 global challenges
P8 is synoptic, drawing on P1-P7 content in real-world contexts. Learn how physics applies to transport, energy resources, climate change, astronomy.
Learn unit conversions
Physics needs unit conversion fluency: J to kJ, W to kW, m to km, s to ms. Drill until automatic.
Master calculations with rearrangement
Many questions require equation rearrangement before substitution. Practise rearranging under time pressure.
