Tips
IGCSE Biology (0610) works outwards from the characteristics of living organisms and cell structure: enzymes, nutrition, transport in plants and animals, disease and immunity, gas exchange, respiration, excretion, coordination, reproduction, inheritance, selection, ecology and human influences on ecosystems.
Biology looks like the subject you can revise by reading. That is the trap. Marks go to precise vocabulary: diffusion is not osmosis, and "the food goes to the cells" will not be credited where "glucose is absorbed into the bloodstream" would be.
Command words matter as much as content — describe and explain are different tasks and are marked differently.
