Hello,

The purpose of the GATE exam is to test students knowledge and understanding of their under Graduate level subjects in Engineering and Science. You are expected to choose papers that are relevant to his / her qualifying Degree. Ultimately, you are free to choose any one or two of the 29 papers as per the combination provided by GATE office. The scorecard of GATE is valid for three years. Your score is only valid when it is above or equal to the score of qualifying marks.

The GATE exam is tough, yes. However, it can be managed with the right preparation. It's also not entirely accurate to say that the GATE exam is tough as a whole. Instead, you should think of the layer-based difficulty, i.e., subjects covered, number of questions answered, time management, and so on.
