With a CRL (Common Rank List) of 59100 and belonging to the General EWS category, securing a Computer Science Engineering (CSE) seat in the top-tier NITs (National Institutes of Technology) and older IIITs (Indian Institutes of Information Technology) will be quite challenging. These prestigious institutes typically have much lower cutoff ranks for the CSE branch, even for the EWS category.

However, your rank does open possibilities in several other engineering colleges. You have a higher chance of getting CSE in some of the newer NITs , such as those located in the North-Eastern states (like NIT Manipur, NIT Arunachal Pradesh, NIT Mizoram, NIT Nagaland), or some of the other less preferred NITs.

You might also have opportunities in some of the Government Funded Technical Institutes (GFTIs) . These are institutions funded by the central or state governments and often have decent academic standards. You would need to check their specific cutoff ranks for CSE for the General EWS category.

Furthermore, explore the possibilities in IIITs that are not among the top-ranked ones . Some of the newer or less popular IIITs might have CSE cutoffs within your rank range for the EWS category.

Finally, consider looking at good state government engineering colleges in your home state (if you haven't mentioned it) or nearby states. Some of these colleges have a good reputation and might have CSE seats available at your rank. Also, research reputable private engineering colleges that accept JEE Main scores, as some might have CSE admissions within your rank range, especially under the EWS quota if applicable.
