<p>Don’t you think you’re just slightly jumping the gun here by trying to figure out what you want to major/minor in, if you’re only a junior in high school?<br>
Perhaps the best way to get some exposure to architecture (both as a discipline and as a profession) would be to take an arch. summer program, talk to local architects &c. You definitely wouldn’t want to jump straight into a B.Arch program only to find out that architecture really isn’t for you.
As you start looking at colleges, just make sure that said schools have a department/degree program in both Arch and Business. But you really shouldn’t pigeon-hole yourself into a major this early on unless you’re 100% sure that this is what you want to do.</p>
