What we predict comes up
From the syllabus weighting and how the papers are usually set. The papers below follow it.
- Plant nutrition and transport in plants16%Photosynthesis with limiting factors, leaf structure and transpiration usually take the biggest single share.
- Reproduction, inheritance, variation and selection12%A monohybrid cross with a genetic diagram, blood groups and natural selection of resistant bacteria are near certain.
- Cells and movement in and out of cells10%Cell structures, magnification and an osmosis experiment with percentage change in mass are favourites.
- Transport in humans and gas exchange10%Heart structure, heart rate with exercise, blood vessels and breathing mechanics are regulars.
