Deepak, good that u know ur weakness and u r ready to learn. Best solution is - practice - practice - practice. Now u need to find where and how - depending on ur own constraints and timings. Some options are - interact with frinds, read english newspapers, talk to others in english, practice mock interview session, participate in events, present in class, etc. All the best for a great career: C2C: Campus 2 Corporate: https://www.facebook.com/groups/a2cskills/
