Hey arbaab,

You can start preparing any time of these 4 years. If you start early then it will be beneficial for you. Syllabus of GATE is not that big if you are starting early. If you are preparing for GATE exam then it will also cover your B.Tech syllabus also. It will benefit in both ways. I suggest you to go through the syllabus and plan accordingly. If in 2nd year the there are 2 subjects in GATE syllabus then study those 2 only not the 3rd year syllabus. And if you want to get admitted in any of the coaching forum then take admission during 3rd year or in 4th year. 

Hope that helps 

All the best

Hello candidate. As you mentioned that you are in 2nd year, just concentrate and read your subjects carefully. Don't bihart go with the concept. There is no need to start gate coaching in 2nd year. Its better to start gate coaching in 3rd year itself as you want to clear in 1st attempt and with good rank. Don't wait until final year better start coaching from 3rd year.
