Which Extracurricular activities can I typically do if I want to learn about engineering?
Engineering is a very broad category of subjects. What subjects within engineering most interest you? I took a programming class at a community college, and studied for and took an AP Computer Science exam (even though that AP course was not offered at my school). If you learn programming, you can build your own projects outside of school. That is harder to do with other engineering disciplines, but you may be able to find competitions, clubs, or other organizations that deal with robotics, civil engineering, or other engineering disciplines.
Thanks, I was thinking of similar concepts also. I want to pursue a mix of economics and computer science. I also love doing design and creating.
