Your Complete PSLE Science 2026 Revision Hub
The PSLE Science paper tests everything you have learned in P3 and P4. It consists of two booklets: Booklet A (multiple-choice questions worth 56 marks) and Booklet B (open-ended questions worth 44 marks). Together, they cover all topics from the MOE Primary Science syllabus — Living Things, Matter, Energy, Forces, and Systems.
To do well in PSLE Science, you need three things: a solid understanding of core concepts, the ability to apply those concepts to new situations, and the skill to communicate your answers clearly in writing. Many students know the facts but lose marks because they do not express their answers precisely. ScienceStar helps you with all three.
Our comprehensive topic notes cover every examinable concept. Our quizzes include both MCQ and structured questions — just like the real exam. Our flashcards help important facts stick in your long-term memory through spaced repetition.
We recommend spending at least 20 minutes per day on science revision in the 3 months leading up to your PSLE. Start with the topics you find most difficult, and use the quiz scores to track your progress. You can do this!
