Before going to the exam students must need to check the syllabus of IBO. The syllabus consists of complete details i.e. name of the chapter and the topics which come in the exam. The complete IBO Syllabus is given below under the table.

Part I- Theoretical Part of IBO

Name of The ChapterName of The Topic
Cell BiologyStructure and Function of CellsMicrobiologyBiotechnology
Plant Anatomy and PhysiologyPhotosynthesis, transpiration and gas exchangeTransport of water, minerals and assimilatesGrowth and developmentReproduction (ferns and mosses included)
Animal Anatomy and PhysiologyDigestion and nutritionRespirationCirculationExcretionRegulation (neural and hormonal)Reproduction and developmentImmunity
EthologyMethodology of EthologyInnate and Learned BehaviourCommunication and social organizationForaging behaviorDefensive behaviorMating systems and Parental careBiological rhythms
Genetics and EvolutionVariationMendelian InheritanceMultiple allelism, recombination, sex linkageHardy-Weinberg principleMechanism of evolution
EcologyIndividual OrganismsPopulationBiotic CommunitiesEcosystemsBiosphere and man
BiosystematicsStructure and functionevolutionary and ecological relationships among typical organisms in the following groups.Knowledge of scientific terms will not be required. However, competitors should know what the named representatives of genera mentioned below look like.The IBO biosystematics list is an integral part of chapter VII in Appendix I of the IBO-Guide.

Part II- Basic Skills For The Practical Part of the IBO

Types of SkillsTopics
Science Process SkillsObservationMeasurementGrouping or ClassificationRelationship findingCalculationData organization and presentation: tables, graph, diagrams and charts, photographsPrediction/ ProjectionHypothesis formulationOperational definition: Scope, condition, assumptionVariable identification and controlExperimentation: experimental design, experimenting, result/ data recording, result interpretation and drawing conclusionsRepresenting numerical results with appropriate accuracy
Basic Biological SkillsObservation of biological objects using magnifying glasses.Work with a microscope (objective max. 45 x)Work with a stereomicroscope Drawing of preparations (from a microscope, etc.)Exact description of a biological drawing using tables of biological terms marked with a numerical code
Biological MethodsFor the IBO exam the competitor should know the following methods and be able to use them.Cytological methodsMethods to study plant anatomy and physiologyMethods to study animal anatomy and physiologyEthological methodsEcological and environmental methodsTaxonomic methods
Physical and Chemical MethodsSeparation techniques: chromatography, filtration, centrifugationStandard tests for monosaccharides, polysaccharides, lipids, protein (Fehling, I2 in KI(aq), biuret)TitrationMeasuring quantities by drip and strip methodsDilution methodsPipetting, including use of micropipettes Microscopy, including use of counting chambers Determination of absorption of lightGel electrophoresis
Microbiological methodsPreparing nutrient mediaAseptic techniques (flaming and heating glass material)Inoculation techniques
Statistical methodsProbability and probability distributionsApplication of mean, median, percentage, variance, standard deviation, standard error, T test, chi-square test
Handling equipmentDue to differences in the equipment between IBO member countries, these skills can only be evaluated if the competitors have been informed beforehand about the algorithm, how to use the equipment, how to proceed with a particular experiment
