That's me. Took plenty of college classes, but never tested well, so never got a degree. I learned most everything on my own, but those classes were a foundation for what I taught myself, and I couldn't have done it without them (as quickly).

This is a good point. I think the structured curricula can be the only way to learn many technical topics, even if you aren’t being formally taught. I also found my time at university to be invaluable for the equipment, facilities, and resources that were made available to me for learning that I could never have provided to myself.
