It is quite ironic that
we are sent to school to learn, and in all of our time there, we are
never taught how to learn.
This is something I have wondered for a long time and I think that if the first couple of years were spent in this area, the entire curriculum time could be near halved. Too much of it is based on if you already have a good memory. That is not education.
I think 50% is very realistic, if those who have mastered accelerated learning techniques are anything to go by.
