NIT

There is not a fix number but several faculty members hold PhDs, including from IITs and NITs, especially in CSE and ECE.

With an SC category rank of 41,242 in JEE Main, it is highly unlikely that you will secure admission to Computer Science Engineering (CSE) or Electronics and Communication Engineering (ECE) in any National Institute of Technology (NIT) through JoSAA counselling. Generally, the closing SC ranks for CSE in NITs range between 1,000 and 6,000, while for ECE, they extend up to around 12,000, depending on the institute and quota. Your rank is significantly beyond these typical cutoffs. Even in CSAB Special Rounds, where vacant seats are filled, the chances of getting CSE or ECE at an NIT with this rank remain extremely low.

With a 72% in your board exam and a 92.9 percentile in JEE Main (Paper 2), getting admission into NIT or VNIT for B.Arch is possible, but might be challenging for top NITs, especially in general category. Your percentile is decent, but the 72% in boards might be a limiting factor as NITs usually require a minimum of 75% (or be in the top 20 percentile). 

With an SC category rank of ninety-three thousand six hundred forty-seven in JEE Mains, securing admission into an NIT, IIEST, or any of the GFTIs will be extremely challenging. These institutions are highly sought-after, and their cut-offs for the SC category are significantly lower, often falling within the top ten to fifteen thousand ranks for most branches. While your General category rank of over ten Lacs further confirms the difficulty, your SC rank is the key factor. For this rank, your best option would be to explore state-level engineering colleges and private universities where admission criteria might be more flexible.

With an OBC-NCL rank of twenty-four thousand four hundred eighty-seven in JEE Mains, you have a very promising chance of securing a seat in several NITs and IIITs across the country. While top-tier NITs and the highly sought-after branches like CSE might be a bit of a stretch, you could definitely aim for branches like Civil, Mechanical, Chemical, or even Electronics and Communication in many of the mid-tier or newer NITs. Similarly, you stand a good chance of admission into various IIITs. It's all about strategic choices during the JoSAA and CSAB counselling processes.

With a rank of 55770 rankand according to the previous trends, you can aim for IIEST Shibpur, NIT AP, NIT Uttarakhand, NIT Srinagar and some other northeastern NITs. You have to sit for CSAB counselling to get these or maybe a better one. Also you can check the details from CSAB official webpage.
