Hi Sufiyan,

Start with the certification courses, workshops or internships (Summer, winter). Participate in your college events as well. Courses completely depends on your interest as which specialization you want to opt while pursuing MBA. 

Try certification courses from my climbers or coursera and for internship you can try through Internshala (It is the best source to do your internship from)

I hope I have cleared your doubt. Wish you all the best.
