I have a bachelor's degree in computer science. I probably learned some topics better than I would have on my own, thanks to being forced to dig deeper for the class. But I was an avid self-studier of computer science, and I learned a whole lot on my own. For the amount of computer science knowledge I need to do my real world work so far, I'm not convinced getting the formal education made a noticeable difference.
That said, I really appreciate all of the other topics I learned in more breadth and/or depth while in college. I learned far more about psychology, linguistics, literature, history, etc., than I would have any time soon on my own. I enjoy reading, and enjoy learning a wide variety of topics, but I tend to hyperfocus on what I feel interested in at the time. I doubt I would have bothered to learn anything about Russian culture or listened to recordings of Jelly Roll Morton if I hadn't been required to for course credit... and I feel better about myself for having learned these things.
And therein lies the real advantage, I think. I may be unschooled, but I am educated. Unfortunately, it's taken me the better part of fifty years to get there. These days my own abilities are severely restricted by Lewy Body Dementia, so I spend my time and energy mentoring young folk -- and none of them will hear me say that a liberal eduction is a waste of time. (And yes -- Jelly Roll, the Cabster and even His Royal Hipness hisself are part of the program.)
Sounds like you went to a great school. Most colleges in India don't allow any flexibility in what courses you can take. You have to pass all the prescribes subjects. Liberal arts? That's unheard of back here.
