Revision checklist

Re-learn the formula sheet actively: v = fλ, ρgh, W = mgh, P = W/t, V = IR, P = VI, F = BIL, Vs/Vp = Ns/Np, Q = mcΔT, half-life halving.
Drill the multi-step electricity questions: series-parallel reduction, then currents and p.d.s through each branch.
Practise explain questions in mark-scheme language: two conditions, three properties, name the rule and apply it.
Refresh the O-Level practical electricity set: fuse choice, earthing, kW h costs, and household hazards.
Finish with radioactivity: balanced nuclear equations, background-corrected half-life calculations, and use-the-right-isotope reasoning.
Sit all twelve chapter quizzes, then this paper in one 120-minute block under exam conditions.

Exam tips

About 1.5 minutes per mark: 80 marks means checking your pace every 20 marks, not every question.
For every calculation, write the formula, the substitution with units, then the answer to 3 s.f.
Explain questions: count the marks and give that many distinct points — one idea per sentence.
If a question mixes topics (a crane with an electromagnet and a motor), answer each part with that part’s own physics, not a blend.

Questions about the Prelim

What is tested in the Sec 4 Physics Prelim?

Everything from Sec 3 and Sec 4: measurement and mechanics, thermal physics, waves and light, lenses, static and current electricity, D.C. circuits, practical electricity, magnetism, electromagnetism, induction and radioactivity — the full O-Level 6091 scope.

How long is the Prelim paper?

Schools differ, but most set an O-Level-style paper: multiple-choice plus structured questions. This practice paper has 80 marks and takes 120 minutes.

Is this paper based on a real school paper?

No. QuizQuip papers are written from scratch against the O-Level 6091 syllabus. QuizQuip is not affiliated with MOE or SEAB and does not host school or past examination papers.
