I am a mechanical student how can i expose my talents?and how should i make my resume more valuable?what are the opportunities are there?

You need to highlight your other talents in extra curricular activities. For Study related talents and specific interest, you can highlight in your educational background section with more emphasis on your preferred subjects.

Hiiii. You are fresher, so you are at base level. yes you can highlight your extra curriculum activity but remember wright the activities which are mostly related to your course. when you will join the company then you will learn many things, then automatically your resume will become more valuable
