Interior design, interior architecture, interior and spatial design, interior environmental design, interior decoration, interior, interior, interior. What is the difference? I didn’t (still don’t) know myself, when my teacher recommended this to me as a course to study at university.

I honestly believe, the only way to really tell which one is best suited for you, me, him or her to study at university is to actually do each course, only then will you know. (Not a very cost effective way at all.)
