Hello  Aspirant,

The authorities will determine the cutoff for IIT Kharagpur after considering various factors such as total number of seats, difficulty level of the Gate exam, total number of registrations and other important things. Candidates who will score equal to or higher than the cutoff marks will be eligible for admissions in M.Tech courses at IIT Kharagpur. Students with higher marks will have a higher chance of admissions through GATE.
