Three days left. Edexcel Paper 1 covers motion and forces, energy, waves, light, and radioactivity in one sitting, so it's wide rather than deep. Here's the order that gets you the most marks.
One focus per day, building to a timed run. Work it in order.
Ranked from analysed past papers. Start at the top: if you run out of time, you will have covered the most-tested ground.
Motion and Forces opens Edexcel Paper 1 and carries the most content of any single topic area on the paper: resultant force, F = ma, and free-body diagrams appear across multiple questions.
Distance-time and velocity-time graphs are tested every year, usually with a gradient or area-under-graph calculation attached to a Newton's second law question.
Edexcel's Conservation of Energy topic is examined as calculations (kinetic energy, GPE, work done) combined with 'describe the energy transfer' questions on the same paper.
Tested through the core practical almost every sitting: a calculation using ΔE = mcΔθ plus a method or evaluation question on reducing heat loss.
The wave speed equation (v = fλ) is applied to both sound and light contexts, and the wave core practical (ripple tank or slinky) is a regular method question.
Ray diagrams for reflection and refraction, plus the refractive index calculation from the core practical, are a consistent source of marks on this paper.
Alpha, beta and gamma properties, nuclear equations, and half-life calculations sit together as one examined block, often worth 6+ marks combined.
Half-life graph reading and calculation questions appear alongside radioactive decay, and are frequently the highest-mark calculation on this section of the paper.
PrepWise has a one-page Knowledge Organiser for every topic above. In your final 3 days, use them the same way each time: cover the page, recall everything you can onto paper, check against the original, then repeat only the bits you missed.
Rules specific to Paper 1. On this paper, structure earns as many marks as knowledge.
Edexcel's equations sheet covers many formulae, but density, efficiency, wave speed and the specific heat capacity equation are ones you're expected to know without looking them up in some question phrasings. Don't waste time searching the sheet for something you should already have memorised.
Write the equation, then substitute the numbers in, then rearrange. Examiners give a mark for correct substitution even if your final rearranged answer is wrong. Rearranging first and substituting last hides your working and loses that mark.
kW to W (×1000), minutes to seconds (×60), cm² to m² (÷10,000), g to kg (÷1000). Do the conversion in a separate line before you touch the main equation. Mixing units mid-calculation is the single most common way to lose an otherwise-correct answer.
'Describe how you would...' questions expect the specific apparatus and steps from the Edexcel core practicals (specific heat capacity, density, wave speed, refraction): control variables, what you measure, and how you calculate the result. Vague answers like 'measure it carefully' score zero.
'State' wants one fact, no explanation. 'Describe' wants a sequence of steps or observations. 'Explain' wants a reason linked to a physics mechanism, using 'because' or 'this means'. Answering an 'explain' question with only a 'state' answer caps your marks well below the total available.
The errors examiners see most on this paper. Each one is an easy mark you already know how to keep.
Forgetting to square v in kinetic energy or squaring the wrong number in ΔE = mcΔθ-style equations → Underline what needs squaring before you substitute. Write Eₖ = ½ × m × v² with v² marked, don't try to do it in your head.
Reading the wrong values off a distance-time or velocity-time graph, especially confusing gradient with area under the graph → Gradient of a distance-time graph gives speed. Gradient of a velocity-time graph gives acceleration. Area under a velocity-time graph gives distance. Say out loud which graph you're looking at before you calculate anything.
Leaving the answer in the wrong unit (e.g. giving energy in kJ or wavelength in cm without converting) → Always write the unit next to your final answer and check it matches what the question asks for. If it doesn't match, you've likely skipped a conversion step.
Mixing up alpha, beta and gamma penetrating power and what stops each one → Learn the trio as one block: alpha stopped by paper, beta stopped by a few mm of aluminium, gamma needs thick lead or concrete to significantly reduce it. Always in that order.
Drawing a refraction ray diagram without a normal line, or measuring the angle from the surface instead of from the normal → Draw the normal as a dashed line at 90 degrees to the boundary first. Every angle in reflection and refraction is measured from the normal, never from the surface itself.
