When you're studying hard engineering, science, or math, it's all the same. It doesn't really matter how many times a liberal political science proffersor goes on MSNBC.
As far as night classes, I'm not a big supporter of that. Over 35 yrs., I've had people working with me that tried to finish their engineering degrees at night, and it's rare when it works out. Usually, the pressure of work and family come in and crushes that effort. But that doesn't mean that someone without a degree, but a willingness to continually learn, can't become pretty successful, once they know the goals.
