Biodiversity and Its Conservation · NEET Botany
What ViJEEta actually holds for this chapter, counted from the live bank — and what it has not measured, marked as not measured.
How many marks is Biodiversity and Its Conservation in NEET?
We haven't measured it, so we print "—". On the JEE side every chapter weight is read from a per-subject weightage file that ships with the JEE bank — each chapter carrying a weight together with the question count and frequency it was derived from — and resolved onto the curriculum tree. No such file exists for NEET. A weightage number is only worth what its denominator is worth — how many papers, how many questions, tagged by what rule — and that pass has not been run on the NEET bank. When it has, the file will ship with all three, and until then this box stays empty on purpose.
What is real for this chapter
507 gradeable NEET questions, of which 404 carry a measured difficulty (an IRT b from the intake calibration), which is what lets a test adapt to you instead of shuffling questions. 280 of them come from the anchor pool — the human-written source content that fills tests and papers before anything else is reached. Those counts are read out of the bank every time this page is rebuilt, so they cannot drift from the product.
What does "mastered" mean here — honestly?
The evidence rules belong to the engine, not the exam, so they are the same ones the JEE side has always used: Biodiversity and Its Conservation shows "—" until you've answered at least 3 questions in it, and after that mastery is a guessing-corrected IRT true score at a conservative ability estimate over the chapter's real item difficulties. Reading theory caps evidence at 0.60, unproctored practice at 0.75; "mastered" (≥0.80) is reachable only through tests.
The one thing that does not exist yet for NEET is the headline readiness score. The JEE /300 is a weighted sum — Σ chapter_weight × mastery — so it cannot be computed without the chapter weights this page has just told you we have not measured. NEET carries the real paper's scale of 720, and per-chapter mastery is measured today; the single NEET number on top of it arrives when the weights underneath it do. Showing a band now would be fabricating one.
Topics inside this chapter
These come from the bank's own topic tags, counted from the questions themselves — not from an editor's chapter plan.
Previous-year questions
42 previous-year NEET questions sit in this chapter's separate PYQ pool, with no paper-year tags on the pool yet, so the year range reads "—". They are never mixed into practice or a test: a question you have already seen has stopped measuring you.
