I got my undergraduate in electrical engineering about five years ago. I design PCBs and industrial circuit now. I can tell you that it just will not click with a single course. In fact, taking a single course, like circuits 1 or electronics 1, will make you hate it. For me it really clicked after taking a circuits 1, circuits 2, and electronics 1. I HATED those classes. Circuits 2 and electronics 1 were really difficult. Eventually, I got to take some embedded circuits and digital design classes that were really cool, but they had to be appreciated. I remember doing a project building a robot that had to figure out how to move through a maze a detect "bombs"(reflective tape) and do a dance and song to get "defuse" them. Lots of fun.

I can keep going, but, in short, I can tell you that you'll have to put in some good work to fully respect and understand the trade. If you want to understand electronics, just do a few projects on your own. Get a beagle board and learn how to flash an LED or print characters to a display. That'll go a lot further than a single class.

Go download EagleCAD. It free and there's tons of tutorials out there. I've used it for a couple projects. OrCAD is much more powerful, though. That's what I use at work.

They're just little project boards.
