Why these tools are different
Most predictors give you one confident number. Real results don't work like that: the same marks can mean very different ranks depending on the shift or the year. Every tool here shows its best estimate and an honest range, and explains where the numbers come from.
We use the latest official NTA data (JEE Main 2026, NEET 2025 and 2026) and update the pages as soon as new data or dates are announced.
