Dear friend
First things first. Improve your English. Even the question you’ve put is in the wrong format.
To be an outstanding student, maintain a good CGPA, i.e., near 80%.
Secondly, be a member of atleast 3 Organising Committees.
Take part and win some position in atleast 2 events every year.
Be an active member in an NGO.
Join some societies and work in it. A position in a society would be really helpful for your CV.
Organise some witty events.
Practice Public Speaking everywhere possible.
Take part and win in quizzes.
Play a sport.
