• GATE Marks out of 100
• GATE Scores out of 1000

A GATE score of 550 in mechanical engineering will fetch you a rank range of 1500 - 3000. Students with this GATE score range can opt for M.Tech at NIT Calicut, NIT Trichy, etc. 

Based on the question paper difficulty level of GATE CS 1 and CS2, it is expected that the normalisation will not be more than +-4 to 5 marks. GATE CSE paper was moderate to tough.
