Predict My CollegeThe BITSAT Biology Syllabus 2026 consists of topics from the higher secondary (NCERT 11th and 12th) biology syllabus. The BITSAT 2026 syllabusfor Biology has been released in the official brochure of the BITSAT 2026 exam. The BITSAT Biology section is not compulsory and is an optional subject; therefore forms only 40 marks out of the total 130 marks comprising the whole paper. The important topics that carry the maximum weightage are the Structure and Function of Plants and Animals, Cell- Unit of Life, Structure and Function, and Reproduction in Animals and Humans.
According to the previous years’ trends, the questions are mostly diagram-based and analytical, paired with a few description questions. The same pattern is expected this year too. The difficulty level ranges from moderate to easy, relating to the previous year’s question papers. Some common topics in the biology section include cells, plant growth, reproduction, and genetics. You are therefore advised to check the BITSAT 2026 exam pattern as well.
Here is the BITSAT 2026 Biology syllabus, with topics and sub topics to provide insights into the key areas of study and essential concepts.
