    Deleted syllabus NEET 2026 Biology

    The National Testing Agency’s official NEET 2026 syllabus PDF, released on May 3, 2026 , removes roughly 15–16 Biology topics — about 5–7% of the Biology content. The cuts are concentrated in Class 11 (about 10 topics) and Class 12 (about 5–6 topics), mainly in plant physiology, taxonomy, ecology and applied biology.

    What the Deleted syllabus NEET 2026 Biology removes

    The classroom impact is specific: Class 11 loses the larger share of deleted items (around 6–7% of the Class 11 portion) while Class 12 reductions account for roughly 3–4% . Major named deletions include Taxonomic Aids and Mineral Nutrition from Class 11, and Reproduction in Organisms and Environmental Issues from Class 12.

    Around 15–16 topics/subtopics were removed in total. Some concepts have been shifted or rewritten in line with NEP 2020 and the new NCERT editions rather than fully deleted. The NTA PDF defines the official list; students should refer to that document for the final word.

    Deleted topics may not generate direct questions, but linked concepts can still appear. Several experts and coaching educators note that conceptual overlaps mean you cannot ignore the basics of removed chapters.

    How Deleted syllabus NEET 2026 Biology affects your preparation

    Biology still carries half the exam weight — 180 marks out of 360 . Class 11 contributes about 45–50% of Biology questions and Class 12 about 50–55% . These proportions remain unchanged despite the small syllabus reduction.

    Study guidance in the official discussion is clear: treat the new NCERT as your primary source and consult the older NCERT editions for topics missing from the new books. Out-of-NCERT items continue to appear occasionally in the NEET syllabus, so cover high-yield extras after finishing NCERT.

    If you are revising, prioritise high-weightage units such as Human Physiology (Class 11) and Genetics & Evolution (Class 12). Practice NCERT-based MCQs and previous-year questions; those patterns still predictably account for most NEET Biology items.

    Quick numbers and next steps

    • Total reduction: ~5–7% of Biology syllabus
    • Topics removed: 15–16 subtopics
    • Class 11: 10 topics (mainly Plant Physiology, Taxonomy)
    • Class 12: 5–6 topics (mainly Ecology, Applied Biology)
    • Biology weight: 180/360 marks

    Students should download the official NTA NEET 2026 syllabus PDF, compare it with both new and old NCERT books, and prioritise NCERT line-by-line study. Keep basic knowledge of deleted topics — related questions could still test linked concepts.
