Why Shift Difficulty Matters for JEE 2025 & 2026?

Students often ask, "Is 150 a good score in JEE Mains?" As the 2025 data clearly shows, the answer depends entirely on your shift.

In 28th Jan S1 (2025), 150 marks would get you ~99.1 percentile (Rank ~14,000).
In 24th Jan S2 (2025), the same 150 marks would drop you to ~95.5 percentile (Rank ~70,000).

This normalization impact is why our Percentile Predictor asks for your shift difficulty (Easy/Moderate/Hard) rather than just marks.
