Singapore N(T)-Level Science: complete 2026 guide to the six topics, the written paper and the practical assessment

Singapore GCE N(T)-Level Science is the everyday-science subject for the Normal Technical course. It builds a practical, working understanding of the world around you: what materials are made of, how energy and forces behave, how electricity reaches your home safely, how your body keeps you alive, and how plants and the environment support life.

This page is the index. Below: the six-topic content breakdown, the written paper and practical assessment structure, a study strategy built for the applied track, and links to every dot-point answer we have shipped for N(T)-Level Science in 2026.

The six topics of N(T)-Level Science

Matter and Materials

What everything is made of. The three states of matter and how they change when heated or cooled, atoms and the difference between elements, compounds and mixtures, how to separate mixtures, common acids and bases around the home, and the everyday metals we rely on.

Energy and its Forms

The different forms energy takes and how it changes from one form to another, the three ways heat travels (conduction, convection and radiation), how electrical energy is used and paid for in the home, and why we should save energy and use renewable sources.

Forces and Motion

Forces as pushes and pulls and what they do, how to work out speed from distance and time, why pressure depends on force and area in solids, liquids and gases, and how simple machines such as levers make work easier.

Electricity and Magnetism

How a simple circuit carries a current, the link between current, voltage and resistance, how magnets and electromagnets work, and the safety features that protect you from electric shock at home.

The Human Body and Health

How the digestive system breaks food down, how the circulatory system moves blood, how the respiratory system gets oxygen into the body, and how a balanced diet and healthy choices help prevent disease.

Plants and Ecosystems

How plants make their own food by photosynthesis, how food chains and food webs pass energy through living things, how water and nutrients are recycled in nature, and how human activity affects the environment.

Assessment structure

N(T)-Level Science is assessed by a written examination paper plus a school-based practical or coursework component. The exact weightings are set by SEAB, so confirm them against the current syllabus.

• Written paper. A multiple-choice section followed by a structured-question section. The questions are short and heavily scaffolded, often built from a diagram, a table or a simple everyday situation. They test recall of key words, understanding of a single idea at a time, and simple one-step calculations.
• Practical or coursework component. A school-assessed component that checks experimental skills: following instructions and working safely, taking simple readings and measurements, recording results clearly in a table, and drawing a straightforward conclusion from what you observed.

The written paper rewards correct key words, clear short explanations and tidy one-step working with units. The practical component rewards safe technique, accurate readings, neat recording and a sensible conclusion that matches the results.

Study strategy

N(T) Science rewards steady, active revision more than last-minute cramming. The recipe:

1. Learn one key word and one example at a time. For each idea, fix the key word (for example "conduction") and one everyday picture of it (a metal spoon getting hot in soup). The example is what makes the word stick and what earns marks in the structured questions.
2. Drill the short structured questions. The exam asks many small parts rather than a few long essays. Practise reading a diagram or table and answering in one or two clear sentences, always with the correct unit on any number.
3. Treat every practical as exam practice. The coursework component is real marks. Each time you do a practical, work safely, take careful readings, record them neatly in a table, and write a one-line conclusion. That habit is exactly what is assessed.
4. Build up topic by topic. Use the dot-point pages below to master one idea, check yourself against the worked answer, then move to the next. Cover all six topics rather than over-revising the one you already like.
