CBSE 12th

Right now, you are pursuing Mass Communication degree of 3 years, and after this you want to pursue a course of wood designing degree of 4 years. I don't think it is a wise choice, because for 7 years you are continuously studying. And, the two things are not related to each other. Rather, I would suggest you to continue with your Mass Communication degree, and side by side do some certificate courses or something like that in designing. So, you will be counted for your experience in designing as well and Mass Communication. You have the degree only, so that's why I believe that if you wish to do these things, then it's not really bad within seven years of studies, and you won't get the returns as you expect, because after 7 years you might or may not have what you expect from doing both these things.
