B.Des (Bachelor of Design) programs at IIT Bombay and IIT Guwahati are both undergraduate programs that focus on design education. However, there may be some differences in terms of the specific curriculum, perspectives, experience, and course offerings at each institution.
Ultimately, how much you gain from this course depends on you only as it all is about learning, observing, and experimenting. No one can help you in design, you have to explore everything on your own.
