Just half? As a software engineer, I have only ever used material from one class I took. It was theory of computation, specifically order notation. The rest of programming is (and was) easily absorbed from books. The actual value of the education was entirely in the weekly problem sets, which demonstrated that I have no valid assessment of my own capabilities: for each, I was certain I could not solve any, but invariably turned them in, complete, the following Monday. Engineering work has been similar.
