AI Create – All About Interior Design

Im a sophmore in highschool, I was origanally going to be an artist, but once I hit middle school I got fashion fever. I sew well, and I consider myself origanal.

What are the steps I need to take to plan a portfolio? How many designs should I have ready to show? How many design boards should I have? Should I make an actual outfit/dress to bring in and show, or wear?

Thanks in advanced!

I’m a sophmore in high school and I want to go to the Art Institute of Pittsburgh and major in Interior Design.
Does anyone go there and could tell me anything?
What is the highest math I should take, and what sciences should I take? I’m in Algebra 2 right now and I can either go on to Pre-Cal and Calculus or take Trigonometry and Senior Math. ( very leaning towards trig and senior math, i hate math ) but I want to be the best at my career.
Any advice of anything having to do with Interior Design is appreciated!
Thanks in advance.
