Dear student,

The maximum marks for CAT is 300. And the maximum  marks for GATE is 100. The qualifying marks for both the exams depends on the overall merit of that particular year, which depends upon the difficulty level of the paper and the total number of students appearing for the examination. Cut offs also vary from college to college, so it is not just about qqualifying but procuring good scores in the same.

*We have assumed that you meant GATE by GAT . Please do rectify us otherwise.

Hope I have answered your query. Please do follow up in case of further questions.

Cheers!
