1 | Curriculum Fit for O-Level Biology
ThatBioTutor's published focus is O-Level Pure Biology, so the first check is fit. For IP students, the useful question is not only whether the topic appears in school, but whether the class gives enough practice in explaining biological ideas clearly under exam conditions.
| O-Level Topic | Why it Matters |
| 1. Cell structure & organisation | Foundation for later systems topics |
| 2. Movement of substances | Explains diffusion, osmosis, active transport |
| 3. Biological molecules | Links chemistry to life processes |
| 4. Nutrition in humans | Covers digestion and balanced diet concepts |
| 5. Transport in humans |
