The 2024 G.C.E. (A/L) Biology Paper II, held by the Department of Examinations, Sri Lanka. Part A: answer all four structured questions (100 marks each). Part B: answer any four of the six essay questions (150 marks each); question 10 is "write short notes on". Answers follow the official marking scheme: in Part A each point earns 1 pt and the 40 points of a question are worth 2½ marks each; in Part B the scheme lists numbered points and the marks are the number of points × 4 (the diagrams in question 5 carry 5 marks each). The English wording here is from the English-medium paper.
