The O Level Biology Practical 2020 series was unique. Conducted during a period of global disruption, the papers focused heavily on core, low-risk experiments that could be managed with minimal equipment. For current students, reviewing the is a goldmine of insight. The questions tested classic skills: food tests, osmosis in plant cells, enzyme activity (catalase), and microscope drawing.
