JEE Main

Yes Sir,
Your son will definitely get into his dream branch in NIT - Warangal as his category rank is better and most students around these ranks go for colleges through JEE Advanced. NIT - Warangal is among the top colleges.
Best of luck to him.

Yes, there are full chances of getting CSE in NITs. You must have to participate in counselling of JEE. Only after counselling, we will get to know about fees concession.

Bro, I suggest you to take admission in any one of your nearest colleges. And do hard work in the computer field that is, learn programming languages and try to make projects based on them. After some time, you will get to know about how companies are doing their work.

With defense quota, you'll get non-technical branches such as instrumentation, manufacturing and automation , Control engineering being from outside Delhi.
If you are from Delhi, you'll likely to get either BIOTECH , CIVIL or MECHANICAL in second or third round.
Best of luck.

Sorry, but you will not be able to get into Nirma Unversity with these marks. Though the selection is dynamic and dependent upon the students applying for it and hence changes every year, still the cutoff for CSE/IT is around 2k and the least non-technical branches is around 80k.

If you want to take admission in NIT/ IIIT / IIT /GFTI, then you need to qualify JEE Mains to get admission.

There are good chances for getting a government seat.

You can look for state engineering colleges accepting JEE Mains score. If you want to pursue engineering from IITs/NITs only than you can also go for one more attempt (if its your first attempt). If you want to do engineering than go for a state engineering institute and work hard. You can try for GATE and again look for IITs/NITs to complete your M.Tech. Just be determined towards your goal. Best of Luck!

Based on your rank, you have good chances to get NITs like Hamirpur, Jaipur, Nagpur, Calicut, Patna, Tiruchirappalli. Other colleges where you have good chances are School of Planning and Architecture-Bhopal, BIT-Mesra, School of Planning and Architecture- Vijayawada.

It is as usual. There is no change. In the future, it may change but for next 2-3 years, it is going to conduct as their usual scheduled calendar.
