I self studied computer science and like the author of the article, working as a software engineer for Amazon. However, despite already working as a software engineer, I decided 6 months ago to return back to university to pursue a CS degree, currently wrapping up two courses — discrete mathematics and computer architecture — offered through University of Northern Iowa via their distance learning program. Although material (e.g. books, online videos) are available (and free), I prefer taking these courses (and receiving the credits) through the university instead of a the self study method due to one reason: feedback from professors. I found it difficult, while self studying, when I was unable to ask someone (who was dedicated) to answering my questions about the textbook or about the lecture or about the homework assignments.
