Hello Isha

I will only suggest you some of the points which will help you to gain confidence while attempting question paper

1. Analyze your target marks bcz many people just think for GATE clearence but they actually dont able to set their target marks .

2. Analyze your strength and weakness .This will help you to gain good marks .You must be confident on the some topics that if they comes in exam then you will score full in that and if some topics you are not good than just learn some basic of it. so if question comes from that topic than you are able to solve that.

3.Confidence on your calculation - Your calculation should be as fast as possible because you will get mininum time period for solving a single question.you can not waste your time on lengthy calculations

at last always be Positive

I hope you agreed with my answer

Thank You
