Hello aspirant,

So you can't pursue interior design course, if you have discontinued your 12th. Mind you on the fact; if you want to pursue the B.SC Interior Design / B.Des Interior Design course, you need to have completed your 10th and 12th from a valid and recognized board plus you must have secured at least 50% in class 12th. Until and unless you complete your 12th, you can't even pursue the course.

Hope, this answer helps you.
