What is not here
We hold a further 2,706 questions where our matcher points at an NCERT section but no human has checked it. Those are not published, because a confidently wrong line is worse than no line. A further 1,162 have no NCERT source we could verify at all, which is a real and unavoidable share of any NEET paper.
How we measure thisNow do it with your own mistakes.
Sit a mock on the real NEET 2027 computer interface. Every mark you drop comes back with the line that would have earned it.
