@sweeetea I took more classes than I needed to my first three years of high school, so I ended up only being required to take english and calculus my senior year. Instead of graduating early, I decided to enroll in my state university and high school at the same time, and take the first year architecture curriculum.
As for telling if you’re cut out for it, I guess it depends from person to person. You should probably have an interest in the sciences as well as the arts. Architecture schools tend to stress a certain kind of conceptual thinking, so make sure that you can think outside the box. I took philosophy courses in high school as well as a three week architecture summer program, which really helped me prepare for the college classes. Take drawing classes, art history, 3d art, or whatever your high school offers on the creative front.
Again, research architecture as much as you can. I used to spend hours just looking at pieces of architecture and reading architecture books. Develop a taste for what you like, what you’re interested in, and some favorite architects/artists/designers.
Again, things are probably different for everyone, this is just some advice I would have given myself a couple of years ago. If you want to talk more, feel free to PM me your email, I’m more than happy to help out aspiring architecture students!
