HSC Biology is structured as a Year 11 Preliminary course followed by the Year 12 HSC course, where final external assessments are completed.

Topics are aligned with the HSC exam structure and can be used directly for targeted practice.

Year 12 (HSC) modules contribute to the final ATAR and focus on exam-level biological analysis and interpretation.

Biology is a single HSC science subject, so the table shows year-based topics rather than Units 1–4 or Areas of Study.

This page focuses on NSW senior Biology topics so conceptual, diagram, and analysis requirements can be compared clearly across Year 11 and Year 12.

Biology Topics and Subtopics

Year 11 = Preliminary · Year 12 = HSC

Pathway	Year 11 (Preliminary)	Year 12 (HSC)
Biology	1. Cells as the Basis of Life text graph diagram analysis • Use cell theory, prokaryotic and eukaryotic cells, organelles, cell membranes, transport across membranes, cell requirements, microscopy, biological drawings, and structure-function relationships.• For harder questions, include cell diagrams, microscopy-style interpretation, experimental data, model comparison, graph interpretation, and explaining how cell structures support function. 2. Cells to Systems text graph diagram analysis • Use levels of organisation from cells to tissues, organs and organ systems, specialised cells, exchange surfaces, transport systems in plants and animals, gas exchange, nutrient distribution, and regulation of internal conditions.• For harder questions, include system diagrams, exchange-surface reasoning, plant/animal comparison, data interpretation, and explaining how biological organisation supports survival. 3. Evolution and Ecosystems text graph diagram analysis • Use classification, biodiversity, adaptations, natural selection, evolution, ecosystem structure, ecological interactions, food webs, energy flow, nutrient cycling, population dynamics, and human impacts on ecosystems.• For harder questions, include ecological data, evolutionary scenarios, food-web diagrams, population graphs, biodiversity evidence, and evaluating cause-effect relationships in ecosystems. 4. Depth Studies and Working Scientifically text graph diagram analysis • Use working scientifically skills across Year 11 Biology: questioning, hypothesis, variables, controls, risk, method design, data collection, uncertainty, graphing, analysis, conclusion, validity, reliability, and communication.• For harder questions, include experimental scenarios, judging method validity, interpreting uncertainty, identifying limitations, improving investigations, and evidence-based conclusions.	1. Heredity text symbol analysis • Use DNA, genes, chromosomes, genomes, inheritance patterns, meiosis, genetic variation, mutation, pedigrees, genetic crosses, genotype-phenotype relationships, and molecular inheritance evidence.• For harder questions, include pedigree analysis, inheritance-pattern identification, genetic cross reasoning, probability-style genetics, DNA sequence interpretation, and evidence-based explanation of heredity. 2. Diseases text graph diagram analysis • Use infectious and non-infectious diseases, pathogens, transmission, prevention, immune responses, vaccination, epidemiology, homeostasis, causes of disease, risk factors, control strategies, and health data interpretation.• For harder questions, include immune-response diagrams, epidemiological graphs, risk-factor data, disease transmission scenarios, evaluating interventions, and explaining disease mechanisms using evidence. 3. Biodiversity text graph analysis • Use genetic, species and ecosystem diversity, evolution, selection pressures, conservation biology, population change, extinction risk, ecological evidence, and management of biodiversity.• For harder questions, include biodiversity data, population graphs, conservation scenarios, genetic-diversity evidence, ecosystem comparisons, and evaluation of management strategies. 4. Biotechnology text diagram analysis • Use biotechnology applications, genetic technologies, DNA analysis, gene expression technologies, disease or biodiversity applications, benefits, risks, limitations, and bioethical considerations.• For harder questions, include biotechnology workflow diagrams, data interpretation, comparing methods, evaluating claims, ethical implications, and explaining how biotechnology evidence supports decisions. 5. Depth Studies and Working Scientifically text analysis • Use working scientifically skills across Year 12 Biology: investigation design, data collection, uncertainty, graphing, analysis, evidence, model evaluation, communication, validity, reliability, and limitations.• For harder questions, include experimental scenarios, uncertainty, evaluating method validity, interpreting trends, identifying limitations, and evidence-based conclusions.
