The course emphasizes how memory works, you would think that to remember things you have to write the information well-enough in it so it sticks. But in reality, the information has been there the first time around the issue for the brain is finding the information like locating a product in a large warehouse.

It is the process of recall that makes things stick to memory as opposed to repeated memorization. Working on several subjects at a time spaces out sessions and prevents the illusion that you have access to the knowledge you worked for when in fact you don't.

Very interesting. Thanks for the info. I honestly haven't given much thought to how much I recall; I figured that I remembered what I remembered and that was that. Perhaps that should receive more attention.

These two blog posts by K. Eric Drexler explain why this is important. It's related to learning subjects you have no familiarity with.
