Hi aspirant, the answer is YES, the thing is student portfolios help them to evaluate the skill in particular design techniques of the student. More often than not, it is also to understand how strongly you are inclined towards design and the particular design discipline you have applied to.

basically not only for B.Des but in every course you portfolio reflects you so if there is necessary(in some where it is not necessary) than you should make the portfolio if not than also you should make the portfolio for future perspective.

Thank You.
