Structures was pretty hard, but only insofar as you had to apply yourself and get the work done. The math wasn't hard at all, it was understanding the direction of forces that was hard-ish. The lab portion where we modeled loaded beams was the hardest part about it, but mostly because the modeling program didn't make sense. Everything else about that class was fun. We got to build stuff, then stack shit on the thing we built and watch it get destroyed. Awesome.
