JEE Main

It is not possible to get into a NIT/CFTI/IIIT. But some regional government engineering college might take you in if you hold some category quota supposedly.
Try your luck or else you can drop a year to get a better rank in JEE next year. If not that, then you always have option to join a private institute.

The minimum eligibility is to get at least 75% in your board exams. Only then you will be getting admission in any NIT, IIT, etc. If you belong to SC/ST then you should have 65% in boards.

It depends upon the rank of JEE Mains. 12th mark is just for your eligibility for JEE Mains. Depending upon the rank do check the JOSAA's previous year opening and closing rank to get an idea of which college and which branch you can apply for. About better courses, CSE and IT are presently the best in terms of placements.

Hi,
It depends upon the rank you got. In accordance with that rank kindly have a look through JoSAA's 2016 opening and closing rank of various colleges to get a rough idea about which govt. colleges you can get. JoSAA is the body that looks over the seat allocation through JEE Mains.

Hello
As you have scored really good marks and have category also you have chances to get DTU but you also have chances for good nits and GFTIs so for you to decide I'm attaching a link, there you can check the opening and closing rank for the various colleges.

And congratulations.
All the best.

I think computer engineering course in Nirma closes maximum at 20,000 - 25,000 rank. Still, you can apply. I would also suggest you apply in 15% NRI category (If you're willing to pay double of the regular fee). Still, let's hope for the best!

You can easily find the list of the best engineering college in all states on Google. It will be a bit difficult to clinch a seat with good branch and college but you can wait until last counseling. Some state also offers quota on the basis of sports and NCC, etc. So you can make a research and plan college accordingly.

It should be less than 35000 for state quota.

Hi,
It will be hard though to get B.Arch as you have not crossed the 75% benchmark for the JEE Mains exam. You can try other fields if you want.

Not possible.
You can't get good colleges.
Try for private colleges.
