hello savita bagoria,

as you're in second year of engineering,you dont need any separate preparation.you've to concentrate in your subjects properly and solve objective type questions by your own regularly.first,take the print out copy of your gate syllabus-subjects.

give some space to this objective type solving section daily.dont distract towards environment,because you're in second year only so you'll be having many distractions.

dont hesitate to ask doubts to your staffs,if they can't clear your doubt then go for online tutorials and youtube but dont get compremised.try to learn deeply, then only you can crack gate.

if you gonna do your preparation like i said,then you can crack not only gate but any PSU's exam.

all the best!
