Once you UNDERSTAND a concept, (any concept) you don't have to remember any formulas. ever. You just derive them as you need them.
I'm afraid (more accurately terrified) that they do not teach this train of thought anymore.
"Same outcome" trumps all. If some in the class (and obviously there will be some), can't grasp the CONCEPT of, say, calculus, none in the class will be allowed to know it (not even talking about mastering it).
Once you are denied a certain level of knowledge/understanding, it is unlikely that you'll be hungry for more.
Thus, a perfect society.
