The assessment of IGCSE Biology (0610) is divided into three main objectives: knowledge with understanding, handling information and problem-solving, and experimental skills and investigations. Each paper is weighted differently based on these objectives:
Paper 1
Only Core students
30% of final grade
Example Question
Organisation of the Organism
Which tissues are found in vascular bundles? a. Palisade mesophyll and phloem b. Palisafe mesophyll and spongy mesophyll c. Phloem and xylem d. Spong mesophyll and xylem
Paper 2
Only Extended students
30% of final grade
Example Question
Biotechnology and Genetic Modification
“Which process makes use of a genetically engineered organism? a. Using bacteria to produce insulin b. Using enzymes in biological washing powders c. Using pectinase in fruit juice production d. Using yeast to produce ethanol”
Paper 3
Only Core students
50% of final grade
Example Question
Gas Exchange and Respiration
(a) A football team has w wins and d draw. The team scores 3 points for each win and 1 point for each draw. Write an expression, in terms of w and d, for the total number of points scored by the team. (b) Athletic, Rovers and United are three football teams. Athletic have a point score of x. Rovers have 12 points more than Athletics point score. United have 3 points fewer than twice Athletics point score. The total point score of all three teams is 121. Use this information to write down an equation in terms of x. Solve your equation to work out the pont score of each team. (c) Simplify 4a - 3b + 5a + 6b 6(2x+1) - 5(x-2) Solve the simultaneous equations. You must show all your working. 3x + 5y = 11 2x - 3y = 20
Paper 4

Example Question
Ecology and the Environment
a. State the genus name of the Mulanje cedar tree. b. Explain the undesirable effects of deforestation on habitats that are on mountains, such as mount Mulanje. c. Scientists in Malawi are working to prevent the extinction of the Mulanje cedar tree in its natural habitat. Explain the benefits to other organisms on Mount Mulanje of conserving the Mulanje cedar tree in its natural habitat. d. The seeds of many endangered tree species are kept in seed banks. Suggest why it is important to collect seeds from many individual trees of each species rather than just one tree.
Paper 5

Is IGCSE Biology Difficult?
IGCSE Biology can be challenging due to the breadth of content covered, ranging from cellular biology to complex ecosystems. It requires a solid understanding of scientific concepts and the ability to apply these concepts in both theoretical and practical contexts. However, with regular study, good organization, and practice in interpreting data and experiments, students can manage the workload effectively. The subject is rewarding for those who have a strong interest in understanding the living world and its processes.
