Hii Gulam...

As you ask about the minimum cut-off marks for GAT PGTA ..to get admission in GITAM university..for M.tech  or M.arch..

The eligibility to get ..M.tech or M.arch through GAT PGTA are:-

To score equivalent grand in the qualifying examination from recognized university with minimmi  60% aggregate mark..and rank obtained in GAT(PGTA ) 2019

But ..GITAM university doesn't publish any kind of cut off marks for GAT PGTA ..as in GITAM ..you can also get admission on management quota....so ..you don't have to bother about your mark in GAT PGTA ..so can get any branch in GITAM university easily....if you perform well in GAT (PGTA)...

Try to scisc above 70 ..to get almost every branch there ....

Hope it will help!!
