The problem
When the NEET 2025 paper is released, there is a race to publish an answer key, and being out first matters. Students mark themselves against that key, so a wrong answer in it is worse than useless to them. Faculty solving a full paper from scratch is slow.
What I built
I ran several models over the paper and combined their answers into a draft key, within hours of the paper releasing. Faculty reviewed it before anything went out.
What changed
Roughly 75% of the answers were right. That is not good enough to publish unreviewed. Faculty got to a finished key sooner than they would have from a blank paper, and the company was first to market.
What I'd do differently
I would send faculty only the questions where the models disagreed. That is probably the useful signal, and it would have been a better use of their time than reviewing everything.
