Exam

You cannot get NIT-DGP for M.Tech without a valid GATE scorecard, you have to score (at least) more than the cut-off marks.

I would suggest you to go with VIT, if you get a seat in CSE and can afford, As VIT is ranked No 1 private Institute by Indian Government 4th time in a row. Coming to placements and curriculum wise it's really excellent. There are top placement record for CSE students offering more than 40L by companies like Microsoft.

Hi,
You are eligible to get admission in this university. But, cut off goes very high. But, I will suggest you to participate in the counselling. And, wait for the last round cut off. If not getting any colleges in last round, then go for private colleges.
Best of luck.

The minimum eligibility for admission in VIT is 60% in class 12th and rank less than 1,00,000 (any campus). But in Bhopal campus, students who got any rank are eligible to take admission, but not sure whether they accept students who have scored less than 60% in class 12th.

Firstly, you need to know what you want to do. If you want to do MBA, then you need job experience. If you want to do MS or Master's degree, then you need to contact the colleges or universities you are targeting and then you will get the required criteria.
Good luck.
