How many NEET questions come from Biological Classification?

Biological Classification has contributed 34 questions to National Eligibility cum Entrance Test (UG) papers between 2016 and 2026 — an average of about 3 questions a year. That count is measured from EByAi’s bank of 46,150 NEET questions, not estimated from a syllabus. Every one of the 34 questions carries a written, step-by-step solution, and each is tagged to Biological Classification within Biology, so you can drill this chapter across every year at once instead of hunting through paper PDFs. Practising a chapter’s full PYQ history is the fastest way to learn the patterns examiners reuse.
