M.Tech

Hi.
JMI take M.tech entry via an entrance exam, the paper can be bought from Makhtab inside the University itself. Hope it helps.

You will not sit for M.Tech placements in IIT but you can Definitely get sit in Other Institutions. Best of luck for your future and if there's any query, feel free to ask.

B.Tech there is Jee mains entrance exam for master degree there is no such requirement.
You can take admission in VIT Vellore on Merit Basis.
Best Of Luck,

You have to go for Gate examination as it is basic criteria for doing M.Tech in engineering college. This criteria is applicable for SVNIT also. So, all the best for future.

Yes,
As you know that KNIT is a part of AICTE approved Institute. That's why it provide stipends.

I'll refer you to join B.Tech CSE rather than integrated 5 year course because if you change your mind in 4th year of your graduation seeing that time scenario then it will be better for you to join MBA or by qualifying GATE you can join any of the PSU because joining integrated course is only beneficial if you have clear goal to join in research or be a professor in any college.
