Start here
Study these chapters first.
Five chapters carry 47.9% of the theory paper — Ch 4 Bioenergetics, Ch 13 Chromosome and DNA, Ch 9 Diversity in Plant Functions, Ch 2 Molecular Biology, Ch 12 Inheritance. Master these first.
The next five — Ch 1 Cells and Sub-Cellular Organelles, Ch 3 Enzymes, Ch 5 Acellular Life, Ch 11 Reproduction, Ch 15 Ecology — add 28.7%, taking the running total to 76.6%.
The remaining chapters share the last 23.4%. LAST here does not mean skip — every one of them can set MCQs and short questions.
