Start here
Study these chapters first.
Five chapters carry 46.2% of the theory paper — Ch 7 Skeletal System of Man, Ch 1 Digestive System of Man, Ch 2 Blood Circulatory System of Man, Ch 3 Respiratory System of Man, Ch 9 Immunity. Master these first.
The next five — Ch 10 Biotechnology, Ch 4 Urinary System of Man, Ch 5 Nervous System of Man, Ch 6 Endocrine System of Man, Ch 13 Climate Change — add 35.7%, taking the running total to 81.8%.
The remaining chapters share the last 18.2%. LAST here does not mean skip — every one of them can set MCQs and short questions.
