What are the courses that i can apply for after XII th (science stream). My interest is in designing(automotive, graphic)

If you're creative, you can also consider going for Design and Animation. However, you must first check if you're suited for Animation. Animation is an art form and a very demanding career. It has ample opportunities for the creatively talented people. Typically you should have good sketching skill

A normal track for science stream would be medicine. In case that doesnot interest you, you should locate your interests.
