Please helpTo became an architect or a set designer what field to take- commerce, art or science.... Which will be the best?
It seems to me that a set designer would want to take art and theater courses. Of course, I would also think that math would be quite important because of layout considerations.
As the previous response indicated, one gets a degree in architecture, and in such a program, most of the coursework is laid out for you. In high school, math is going to be quite important, and you would do well to get high grades in math. In addition to the above-mentioned coursework, world cultures would be a good area, because architecture, in addition to being a combination of art and engineering, is also a form of culture.
I agree especially with # 3. The students I know who are becoming set designers have worked extensively in theater. They have taken theater courses and have been involved in the production of plays. Such work can begin as early as high school. Courses in art might be especially helpful for someone wanting to be an architect; pre-engineering courses might also help.
Your best bet would be to search colleges and universities which specialize in the areas of your interest. Find a school which appeals to you both culturally and according to other interests (college life, extra-curricular, etc.) Once you find a school, you can contact the department and ask them the best way to obtain your goals.
It is a good suggestion to try to be around people in the field in which you are interested. For, sometimes there is, indeed, a large gap between the idea and the reality. Visiting colleges and talking with representatives of these colleges is also a good beginning point.
My daughter's friend is doing an architecture degree at university and previously her subjects were Art,Maths and Product Design. Other useful subjects would be History, Physics and Information Technology, so basically - a mixture!
