Hello Aspirant,

First, you have to clear the cut off to get a call for the GD and PI. The cut off depends upon the gate score, not on the marks. The GATE score cut off varies from around 650–700 depending upon the no. of applications.

Though Gate score vary year to year still I can give you a rough figure as per last 2-3 years Gate score scenario - 

General Category -720-750(Minimum)

OBC -650-680(Minimum)

ST/SC-480- 550(Minimum)

Secondly, after the call, you have to crack the GD and PI round to get into the college.

Hope this helps.
