A manageable Foundation pair with precision traps
These are the June 2025 J249/01 and J249/02 Foundation papers, each worth 90 marks and lasting 105 minutes. Overall difficulty is estimated as moderate for Foundation candidates. Selection tasks and familiar calculations provide an accessible starting point, while linked calculations, standard form and two extended responses demand more care. This judgement comes from the tasks and marking requirements, not candidate results: the supplied documents contain mark schemes but no examiner report.
Where revision pays off
Simple circuits and Powering Earth offer substantial subject coverage. The particle model is also prominent, including atomic structure and density. Practical skills recur across both papers through apparatus choice, risk reduction, measurement methods and evaluation. Practise explaining what you measure, which instrument you use and how the measurements produce the required result. Topic totals here assign each part once; practical questions can therefore reinforce science beyond their primary chapter label.
For calculations, write the relationship, rearrange it if necessary, substitute values with consistent units and then evaluate. The equation sheet helps with recall, but choosing and using a relationship still matters. Check prefixes, minutes versus seconds and significant figures before moving on. In linked parts, retain your earlier answer and show the next method: the schemes explicitly permit error carried forward in several places.
Precision that earns credit
The marking guidance rewards a graph description that gives both the direction of change and how its rate changes. A curve rising more steeply is not directly proportional simply because both quantities increase. For a distance–time graph, separate each stage, connect gradient to speed and support your account with calculations. A horizontal section represents no change in distance.
Keep related ideas distinct. Elastic deformation does not automatically mean Hooke’s law applies. Irradiation concerns exposure to radiation; contamination concerns radioactive material reaching a person or surface. Wave vibrations must be described relative to the direction of travel. For practical evaluation, identify a specific problem and a matching improvement: vague references to human error or repeating measurements do not always address the weakness being tested. These are mark-scheme-based cautions, not claims about how frequently candidates made mistakes.
A practical exam routine
Aim for about 20 minutes on the multiple-choice section of each paper, leaving roughly 75 minutes for structured responses and ten minutes to check. The paper permits a maximum of 30 minutes for Section A. Attempt every item. In each six-mark response, address all requested strands and connect evidence to your explanation; isolated facts may not meet the higher level descriptors.
Preparing for the next series
The earlier history supports sustained attention to circuits, waves, forces and energy supply. Uses of magnetism and changes of state receive lighter coverage here than in the earlier totals, so keep their wider content in revision. Missing history entries are not confirmed zeros. Several historical gaps, including static charge and basic magnetism, are already revisited in 2025. Prediction scores are revision priorities rather than measured probabilities: use them to order practice, never to remove chapters from your plan.
