Class 11

No, you can't but you can prepare for it and by the time you'll be in class 12th you can give the exam, before clearing and after clearing 12th.

There are scholarships also available in different institutes for different and some specialised groups, which can be inquired at the time of admission to the institute or college. The subjects covered in these courses are art and basic design, furniture design, computer-aided design, furnishings, and fittings, etc.

Hello Harith
It is your interest in 'art and design' which made you decide that you wish to move forward in this field. So, as far as the choice of subject in class 11 is concerned, I would say you may choose any stream of your interest but just stay in touch with arts, gain more knowledge in arts and connect with it through regular activities despite the stream you choose. All the best.
