Revision checklist

Practise resultant forces and pressure = force ÷ area.
Revise conduction, convection and radiation with one example of each.
Recall rusting, neutralisation, and how to tell a chemical change.
Read a food chain and predict what happens if one population changes.
Draw a series and a parallel circuit, and state what a fuse and an earth wire do.
Revise enzymes and absorption, xylem and blood, and where fertilisation happens.
Sit this paper in 1 hour 30 minutes, then mark it and redo the questions you lost marks on.

Exam tips

Spend about one and a half minutes per mark.
In a series circuit the current is the same all the way around.
Food-chain arrows point from food to feeder.
Name the organ and the job. “The body digests food” is too vague.

Questions about the EOY

What is the format of the Sec 2 Science EOY exam?

It varies by school. This practice paper has 20 multiple-choice questions (20 marks) and structured questions (40 marks), to be done in 1 hour 30 minutes.

Which chapters are in the Sec 2 EOY?

In the usual G2/G3 scheme the paper covers syllabus topics 9–16, shown here as Sec 2 Chapters 1–8. Yio Chu Kang Secondary’s Sec 2 G3 end-of-year information for 2025 and 2026 lists forces, heat, chemical changes, ecosystems, electrical systems, digestion, transport and reproduction. Bartley Secondary’s 2025 paper uses the same Sec 2 topics and also some earlier ones.

Does the Sec 2 EOY include Sec 1 topics?

Some schools do set a few Sec 1 topics again. This practice paper does not. Use the Sec 1 end-of-year paper if you need Chapters 1–8 of Sec 1.
