With an ST rank of 25,678 in JEE Mains 2025, you have a possibility of getting into some NITs, but the chances for the top NITs, especially for core branches like Computer Science, will be quite competitive. The actual cutoffs vary each year depending on the number of applicants, their performance, and the seat matrix.

Considering your ST rank and the home state quota for NIT Jamshedpur , your chances of securing a seat are better compared to the other state quota. Based on the previous year's cutoff trends, for the ST category under the home state quota at NIT Jamshedpur, the closing ranks for some branches have gone up to the 40,000s and even higher for less popular branches. Therefore, with a rank of 25,678, you might have a good chance of getting into branches like Metallurgical and Materials Engineering, Production and Industrial Engineering, Civil Engineering, or even Mechanical Engineering at NIT Jamshedpur under the ST home state quota. However, for the more sought-after branches like Computer Science or Electronics and Communication Engineering, the closing ranks for the ST home state quota are typically much lower, so the chances might be slim.

Regarding your CRL rank of 9,33,546, it is very unlikely that you will get any NIT through CSAB counselling. CSAB (Central Seat Allocation Board) conducts special rounds of counselling to fill the vacant seats after the regular JoSAA rounds. The ranks for admission through CSAB usually remain within a few lakhs for the general categories, and for reserved categories, they might go slightly higher, but not as high as 9 lakhs. With a CRL rank of 9,33,546, your rank is considerably outside the typical range for admissions into NITs, IIITs, or GFTIs (Government Funded Technical Institutes) through CSAB.

In summary, while your ST rank of 25,678 gives you a reasonable chance of getting into NIT Jamshedpur under the ST and home state quota for some branches, your CRL rank of 9,33,546 makes it improbable to secure a seat in any NIT through CSAB counselling. It would be advisable to focus on the JoSAA counselling based on your ST category rank and explore the options available to you in NIT Jamshedpur and possibly other NITs that accept a higher ST rank for certain branches.

I hope this helps.
