O Level Science (Chemistry/ Biology)
Combined Science (Chemistry & Biology) equips students with essential scientific literacy across two core disciplines. The syllabus focuses on foundational chemical principles and biological processes, helping students understand how matter behaves, how living organisms function, and how both interact in real-world environments.
Students develop the ability to interpret data, explain scientific phenomena, and apply key concepts to daily life, from chemical reactions and energy changes, to human physiology and ecosystems. The course strengthens logical reasoning, observation skills, and exam techniques needed to succeed in the O-Level Combined Science papers.
