Free GCSE combined science practice for Year 11, nine months out from the May/June 2027 exams. Every question below comes from GradeNinja's own bank - 2,705 Science questions across 59 topics.
Combined science covers biology, chemistry and physics across a shared set of papers, which means the same total revision spread over three subjects' worth of content. Coverage matters more than depth here.
Rotate all three rather than blocking one at a time. Spacing the three sciences against each other is more effective than a fortnight of pure biology followed by a fortnight of pure chemistry.
Our Science questions are not tagged to a single exam board, because the underlying content overlaps heavily across boards. Check your own specification for board-specific requirements.
Answer before you open the explanation. The moment of not-quite-knowing is the part that does the work, and skipping to the answer skips the learning.
Anything you get wrong, come back to tomorrow rather than immediately. Getting it right straight after seeing the answer proves nothing.

The distance of the light from the pondweed.
The distance of the light source from the pondweed changes the light intensity (light intensity is inversely proportional to distance squared). This is the independent variable.
Liquids with different boiling points
Fractional distillation separates liquids that have different boiling points, for example the different fractions in crude oil.
10 m/s
When two objects move in the same direction, their relative speed is the difference of their speeds: 25 − 15 = 10 m/s. The faster car gains on the slower one at 10 m/s.
Electron
An electron has a relative mass of approximately 1/1836 (negligible compared to protons/neutrons) and a relative charge of -1.
Pulmonary circuit
The pulmonary circuit carries deoxygenated blood from the heart to the lungs, where it picks up oxygen, then returns to the heart.
25%
Efficiency = (useful output / total input) × 100% = (500/2000) × 100% = 25%.
Damp litmus paper is bleached white.
Chlorine gas bleaches damp litmus paper white (or turns damp blue litmus red then bleaches it). Squeaky pop = hydrogen, glowing splint relights = oxygen, limewater turning milky = carbon dioxide.
Bicep
The bicep is the flexor muscle of the arm. It contracts to bend (flex) the arm at the elbow, while the tricep relaxes.

Start revising free →Short, frequent sessions of active recall beat long sessions of re-reading. Test yourself, check, and revisit anything you got wrong a day or two later rather than immediately.
They are not tagged to a single board, because the content overlaps heavily across boards at GCSE. Check your own specification for board-specific requirements.
GCSEs are sat across May and June, so for the current Year 11 that means May/June 2027. Exact paper dates come from the exam boards and your school.
