The only thing that made me think was that all that class he was saying about Acing a test because you memorized stuff and these methods to "learn stuff faster". But I always kept thinking that it's not learning, it's memorizing. And how different these two are.
For example, I can learn the properties of distribution in math by understanding how Algebra works and the proof that shows how we get there, and never forget it. OR, I can memorize it using the Acronym FOIL (First, outside, something, left... I don't know) and never forget. But they are totally different things.
I will never forget what I read (in one of the only books I read) in one of the books of Sherlok Homes where he said that our brain is like a basement of a house. You can keep saving stuff in, but eventually you will start running out of space. That is why he would only "learn" useful things for him, but he would careless about what are the planets on the Solar System.
Note: The best part of all this, I was trying to remember what's the name of these "techniques", but I forgot it.
