The Process of Ultra Learning and Rable Difficulty

I think the process of ultra learning combined with rable difficulty produces something like cramming. Anybody who has ever stayed up the night before a test to cram and then passed the exam recognizes that that helps you in the short term, maybe not so much. So i don't know exactly. He does kind of say later on that cramming is really not the right approach here,. But in this dissection non desirable difficulty, it sounds like the goal being to pass a test. Ye, go ahead, sure.
