I'm looking to start studying computer science and since I'm already working full time, I would like to do it online in my free time. I was looking at some bachelor's degree online but they are often pretty expensive and unaccessible. On the other hand, there are a lot of free resources online, but that often cover a single topic, without providing an understanding of the holistic learning path and which matters/topics to study.

I don't care to actually enrol in a bachelor in order to obtain a degree certificate, but I need a course that gives me a comprehensive syllabus of the topics I should learn and eventually where to find them (if not included in the course).

Any idea/suggestion? Thanks!
