ISC Biology Exam 2026: Important topics

Students preparing for the ISC Class 12 Biology examination should pay special attention to the following core units, which carry significant weightage in the question paper:

  • Genetics and Evolution: This unit generally carries the highest weightage in the paper and includes analytical and problem-based questions related to heredity, variation, and evolutionary concepts.
  • Reproduction: Questions from this section focus on reproductive processes in humans and other organisms. Though detail-oriented, it is considered a scoring unit if concepts are clearly revised.
  • Biotechnology: This topic usually includes straightforward questions on biotechnology principles and their real-world applications, making it relatively predictable for students.
  • Ecology and Environment: Despite often being overlooked by students, this unit appears regularly in the exam with questions related to ecosystems, environmental issues, and biodiversity.
  • Biology and Human Welfare: This section covers topics linked to human health, diseases, and the role of microbes in medicine and welfare.
