Please advice under which head i should show my income

I work as freelancer online and have clients from different country around the world............but i do this work as part time and i am still a student preparing for Competitive exams like SSC and Bank........... My question is under which head should i show the income in the return (my expected income at the end of March 17 will be around Rs. 4.5 - 5 lakhs). I am confused between either should i show it under Business and profession or Income from other sources
