GATE Scores

Hi,
The minimum score is around 40-50.

Just go to their official website.

GATE exam is for M.Tech. And, if you do not have GATE score you cannot take admission in premium institutes. But, many other universities that conduct their own exam for M.Tech. Hope this help you.

All private universities and colleges generally don't require any GATE scorecard. So you need not worry but carefully select a college that has a good placement record and studies.

No, qualification required is GATE.

What is your branch? This is important and different PSU having different cutoff marks and rank. Like for mechanical the rank up to 1500 sometimes.

It depends upon your branch and the rank in GATE. Year on year cutoff and highest score in GATE is increasing, so it is different but for civil approximately 65-70 marks are for a good IITS.
