Dropped from the official key and left out of every count: Q8, Q18.

Questions from the official NEET UG papers published by NTA (CBSE before 2019). Topic and idea tags, difficulty and notes are Lumi’s.

Other papers

Every NEET paper, 2017 to 2026

NEET 2018 →

How is difficulty decided?

Each question is rated easy, medium or hard by how many steps and how much recall it needs. It is Lumi’s rating, not NTA’s, and it is the same scale for every year.

What is a “new idea”?

Inside each topic we tag the exact idea a question tests. A new idea is one that no earlier paper in our data had tested. The first year, 2017, has nothing to compare with.

Does this tell me what will come next year?

No. It shows weightage and patterns from past papers. Chapters and topics repeat; exact questions rarely do.
