I'm sorry, I don't understand what you are getting at. With the internet in it's current state, notes from college years 1&2 are useless... I could go on Wikipedia and YouTube and get the same, if not higher quality, information about those subjects. FWIW, I still have all of those notes. The understanding and intuitive development is what suffers, not having the information available.

You do not develop understanding by merely looking up resources and reading about it.

Reading something alone will create not create fluency and understanding.

That is why we take notes. They serve both as records of what we learned, a learning tools, and a place to synthesize knowledge and understanding.

I also use wikipedia and lookup youtube videos, but I don't merely read or watch about it. I engage in an active process of learning and synthesizing information.
