BFA

Sorry, now changing of the course will not be possible. Doing so will be a waste of a year.
It would be better complete B.Com.

BFA Animation is a 4 year Degree whereas B.Sc/ BA Animation is 3 years. BFA Animation would give you more time to learn. However, 3 years degree can be followed by a 1 year stint in a studio which allows you to be ahead in terms of your career.

The best option is to ask the current 1st year students for the same.

There will be an aptitude test where you will be evaluated on the basis of your painting, sculpture and designing skills. Practice drawing and painting, sculpting objects from daily life. You can use scrap objects to create sculptures. Focus on color, light and shadows. In painting experiment by mixing colors to create other colors (ex- mix yellow+red to create orange). Do not use black for shade or darkness.

Yes, you can do that as University Grants Commission has given a go ahead to students to pursue two-degree programmes simultaneously.

Hello Nishant,
B.Tech is much more prestigious and more sought after degree worldwide, so it will be better for you to stick with CSE rather than switching your self to BFA.

The course is worth pursuing if you are aspiring to explore new skills of communication through digital arts and cultivate a creative potential for innovative media.
