I'm wondering about how hard it is in graduate school. I really want to learn how to build things, but I'm not exactly a genius. I've only taken Calculus I which I got a B in. I understood all the concepts well but had trouble with the word problems. I got better at doing the word problems in time though, but I'm not that great at critical thinking. I got a 650 on the SAT math if that tells you anything. Is structural engineering mostly memorizing concepts and formulas and applying them or is it full of really tough critical thinking problems. I'm definitely willing to put as much work is needed though, and I'm guessing my critical thinking skills will increase the more engineering and physics classes I take. Mostly, I want to know if its worth trying or if I should do business or computer science.
