Should I opt for commerce stream in HSC, I want to pursue mass communication in UG? Is it a good decision?

Dear, Yes, that will be wise decision because if in the future, your interest would be lost in mass communication, you can think of other programme too. If you can manage, add maths subject. And programmes like: Economics Hons B.com Hons BBA BBALLB or BCOM LLB CA Maths or statistics Hons Actuari
