It includes multiple-choice tick-box questions, short answer definitions, and explanation prompts requiring clear reasoning and calculations where appropriate. The paper also tests experimental method choices, controls in pH investigations, interpreting figures and micrographs, and understanding vaccination responses over time.","AQA  \nGCSE  \nBiology  \nSET B – Paper 1 Author: Kath Skillern  \nHigher Tier  \nH  \nMaterials Time allowed: 1 hour 45 minutes  \nFor this paper you must have:  \n• a ruler  \n• a calculator.  \nInstructions  \n• Answer all questions in the spaces provided.  \n• Do all rough work in this book.
