I'm not in the CIS program, but I am a Penn Foster College student (AS in Marketing). I write the blog here at eLearners called My Penn Foster College Experience, and my wife is a student of Penn Foster Career School. We both enjoy studying with Penn Foster very much. My wife and I have learned a great deal since we began our studies. I have noticed that my studies have helped me with my job performance, and I changed careers a couple of years ago. I believe I was hired in part because I was studying in a degree program. After I get my AS from Penn Foster, I plan to get a BA in Communications.
There are many Penn Foster students who read this message board. I'm sure one of them can tell you something about the specific program you are interested in. PFC courses are more correspondence courses than they are online. I study from books and study guides, but take most of my exams online. That's really the only "online" component to my program.
Let me know if you have any questions, but I highly recommend Penn Foster College.
