Exam structure

OCR Gateway Physics A is assessed by two written papers, both sat at the end of the course, and is tiered into Foundation (designed for grades 5 to 1) and Higher (designed for grades 9 to 4). A learner is entered for one tier only.

  • Foundation: Paper J249/01 (P1 to P4) and Paper J249/02 (P5 to P8). Each is 1 hour 45 minutes, 90 marks, 50%.
  • Higher: Paper J249/03 (P1 to P4) and Paper J249/04 (P5 to P8). Each is 1 hour 45 minutes, 90 marks, 50%.

Every paper has a Section A of 15 marks of multiple choice and a Section B of 75 marks of short answer, structured, maths and practical questions, including a six-mark level of response question. The Paper 2 or Paper 4 side is synoptic and assumes the P1 to P4 content. A calculator is allowed throughout, and an equation and data sheet is provided.

Practical activity groups

OCR sets practical activity groups (PAGs) that centres deliver during the course. For physics these cover measuring density, investigating force and extension for a spring (Hooke's law), investigating acceleration and motion, investigating waves in a ripple tank and on a string, measuring specific heat capacity, investigating the I-V characteristics and resistance of components, investigating current and potential difference in series and parallel circuits, and investigating reflection and refraction of light. There is no separate practical exam; instead, at least 15% of the marks in the written papers assess practical skills, sampled from these activities and from the apparatus and techniques list.

How to study OCR Physics A

Physics rewards confident calculation, precise definitions, and clear diagrams.

  1. Work from the specification statements. Each point in P1 to P8 is a checklist; questions are written from them.
  2. Drill the maths. With a large share of marks mathematical, rearranging equations, substituting with units, and reading graphs must be automatic.
  3. Learn the recall equations, and find the given ones fast. Memorise the recall list, and practise locating and using the data-sheet equations.
  4. Master the practical activities. The methods, apparatus and sources of error recur across both papers.
  5. Match the command words. State and Describe want concise recall and observation; Explain wants a cause-and-effect chain; Evaluate wants a balanced judgement.

The eight topics, dot point by dot point

Each topic has specification-statement-level answer pages with worked exam questions and cross-links, plus an overview guide and a quiz. Browse the full set at /gcse-ocr/physics/syllabus.

For the official specification

OCR publishes the full specification (J249), past papers, mark schemes and the practical handbook at ocr.org.uk. Always revise from the current specification and OCR's own past papers, because question style, the tiering and the equation sheet are board-specific.

Common questions about Physics

How is OCR Gateway GCSE Physics A (J249) structured?
OCR Gateway Physics A (J249) is the separate (triple) Physics GCSE, worth one GCSE on the 9 to 1 scale. The content is split into eight topics: P1 Matter, P2 Forces, P3 Electricity, P4 Magnetism and magnetic fields, P5 Waves in matter, P6 Radioactivity, P7 Energy and P8 Global challenges, plus P9 Practical skills, which is assessed through questions in every written paper. It is examined by two written papers at one tier, with no coursework grade.
What are the OCR Gateway Physics A exam papers?
Foundation candidates sit J249/01 and J249/02; Higher candidates sit J249/03 and J249/04. Each paper is 1 hour 45 minutes, worth 90 marks and 50% of the GCSE. The Paper 1 or Paper 3 side assesses P1 to P4; the Paper 2 or Paper 4 side assesses P5 to P8 and assumes the earlier content. Each paper has a Section A of 15 marks of multiple choice and a Section B of 75 marks of short answer, structured, maths and practical questions, including a six-mark level of response question.
Which equations must I recall for OCR Physics A, and which are given?
You must recall equations such as speed equals distance over time, acceleration, force equals mass times acceleration, weight, work done, power, kinetic energy, gravitational potential energy, density, charge equals current times time, potential difference equals current times resistance, the two power equations, the wave speed equation and momentum. You are given on the data sheet equations such as the SUVAT equation (Higher only), specific heat capacity, specific latent heat, force on a spring, pressure due to a column of liquid and magnification.
What are the practical activity groups (PAGs) in OCR Physics A?
OCR sets practical activity groups that centres deliver, covering density, force and extension for a spring (Hooke's law), acceleration and motion, waves in a ripple tank and on a string, specific heat capacity, the I-V characteristics and resistance of components, current and potential difference in series and parallel circuits, and reflection and refraction of light. There is no separate practical exam; at least 15% of the written marks assess practical skills sampled from these activities.
How much maths is in OCR Gateway Physics A?
Physics has the highest maths demand of the three sciences, with a large share of marks assessing mathematical skills. Expect rearranging equations, substituting values with correct units, working in standard form and with SI prefixes, reading gradients and areas from distance-time and velocity-time graphs, and ratio and percentage work. A calculator is allowed in every paper, and an equation and data sheet is provided, though many equations must be recalled.
How should I revise OCR Gateway Physics A?
Work topic by topic against the P1 to P8 specification statements, because questions are written directly from them. Drill the recall equations and rearranging until automatic, learn the data-sheet equations so you can find and use them quickly, learn the practical-activity methods and their sources of error, and practise reading graphs. Learn key definitions precisely for the State and Describe command words, and attempt OCR past papers for your tier under timed conditions.
How do I approach projectile motion problems?
Split the motion into horizontal (constant velocity) and vertical (constant acceleration due to gravity). Use t as the shared variable across both axes.
What's the difference between work and power?
Work (J) is energy transferred by a force over a distance. Power (W) is the rate of doing work β€” work divided by time.
When is momentum conserved?
In any collision (elastic or inelastic) where no external net force acts on the system. Kinetic energy is only conserved in elastic collisions.
What's the photoelectric effect?
Light shone on a metal can eject electrons, but only if the photon energy (hf) exceeds the work function. The kinetic energy of the ejected electron is hf - W. Evidence that light behaves as discrete quanta (photons).
How do magnetic forces on current-carrying wires work?
F = BIL sin ΞΈ for a wire in a uniform field B with current I and length L. Direction comes from the right-hand rule. Underpins motors, generators, and ammeters.
