NIT

Yes, you can get NIT for engineering but you have to qualify JEE Mains and Advanced for the same.

You got a decent score. You will get top 10 NITs. Please provide your rank for the best suggestions. By the way, you will easily get into a good NIT. Thapar University and IIIT-Bangalore are also a very good option at this score.

Hello Keshav,
As per your marks, your chances are very slim to get NITs and good govt. colleges. Try for private colleges.
All the best.

Hello Harsha,
You have mentioned your caste but you have not mentioned if you are eligible for admission under any quota. However, don't worry. I am attaching a link that will predict college for you.

Hello Aditya,
It will not affect. But why gap of two years? Even in one year, you can become master of the syllabus. Your academic record will surely be scrutinised and you should have answers for your breaks. That's all.

Absolutely, there will be good future if you study in NIT but for job opportunities, you should try abroad for better salary packages. You can get nice salary packages in North India.

Not at all. There are students from various fields like commerce, arts, medical, as well as Non-IIT's and Non-NIT's.

Hi Ibrahim,
The official cut-off marks for this year (2017) has not been released. So you may refer to the link below which gives the opening and closing ranks for the year 2016:
http://josaa.nic.in/Result2016/result/OpeningClosingRank.aspx
This year, the cut-offs have gone down so that there are many chances for a person with a mark above 100 to easily get an NIT.
The closing and opening ranks vary each year. It will not be a constant.
All the best.

Maybe, may not be. If you belong to the SC/ST category then you will get it. You will get integrated B.Sc-M.Sc if you are from general category. NIT, Patna, Agartala and NIT-Rourkela provide this course.
Hope it helped.
All the best.

No, actually, the real reason why they are upper in rank is that the total number of research papers published, number of placements, number of GRE and GMAT qualifiers and many other factors form that ranking.
