The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2025 Chemistry Equilibrium PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2025 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
