Ma 12th ka baad Interior designers ki study karugi toh 10th ka baad kya best rahega 1.SCIENCE 2.COMMERCE 3.Arts 4.DIPLOMA
You can take whichever stream you want to take or you are interested in because students who have passed Class 12th or equivalent qualifying examination can pursue the B. Des course.
There is no restriction of stream at 10+2 level therefore; you can pursue the course irrespective of streams i.e. Science, Commerce, Arts and Humanities.
All the best!!
