IB Biology equips students with the knowledge and skills to investigate the living world. This includes the study of all levels using many different approaches and techniques. Through studying Biology, students should become aware of how scientists work with each other. While the scientific method may take on a wide variety of forms, the emphasis is on a practical approach. In addition, through the theme of the “Nature of Science”, the knowledge and skills will be put into context. Besides, there are 2 different levels offered, Higher Level (HL) and Standard Level (SL). Our experienced trainers will walk you through the key concepts as well as applications in examples. Our course structure for the 2 levels can be found below. Check them out!
Biology Standard Level

| Genetics | Genes, chromosomes, meiosis, inheritance, genetic modification and biotechnology | |
| 2 | Ecology | Species, communities and ecosystems, energy flow, carbon cycling, climate change |
| Evolution and biodiversity | Evidence for evolution, natural selection, classification and biodiversity cladistics | |
| Human physiology | Digestion and absorption, the blood system, defence against infectious diseases, gas exchange, neurons and synapses, Hormones, homeostasis and reproduction | |
| Sessions for option curriculum (Both SL and HL pick one): | ||
| Session | Topic | Subtopics |
