I have secured 60 marks in gat can i expect admission in gitam
Considering the last 3 to 4 year's trend, yes you can get GITAM.
With 70+ marks various Students got CSE in GITAM and that too Campus of their Choice last to last year.
In short you just need 60+ marks to get GITAM and yes don't be surprised if you could get CSE, who knows...
BTW, you can even get GITAM via Management Quota.
