Hello, I'm a sophomore in college getting a dual degree in mechanical/aerospace engineering. I pretty much know everything we're doing in classes or everything is really easy so I have a lot of free time on my hands. What do you think I can do that will help me in my future career? I was thinking about getting a program like mathematica and playing around with it or reading online about engines and how they work and stuff but I think I'll just learn about those things down the road. What do you think?
