Secondary 4 Physics – LearnSphere

About Course

This course is designed for Secondary 4 students preparing for the O-Level Physics exam under the MOE Singapore-Cambridge syllabus. Building on the fundamentals from Sec 3, this course explores electricity, electromagnetism, waves, and practical electricity in greater depth.

Learners will analyse real-world systems using concepts like current, voltage, magnetic fields, and electromagnetic induction. Each topic is structured to strengthen problem-solving skills, deepen conceptual clarity, and prepare students for practical and theoretical exam questions.

Through expert-led video lessons, downloadable worksheets, and interactive quizzes, students will gain the confidence and competence to master upper secondary Physics.
