515 real JEE Advanced questions (2016–2023). Every question links to others that test the same idea, found by comparing question embeddings — computed locally on this laptop, since no ready-made JEE Advanced dataset ships them.
Two honest limits of this dataset, unlike the JEE Main explorer: there is no worked solution here — "Reveal" shows only the final answer, so check your own working against it, not a step-by-step. And there is no topic tag at all — filtering below is by subject only (Physics / Chemistry / Mathematics), not sub-topic.
