The question that came to my mind was "how do we give children the opportunity to think through problems which cannot be processed in two hours?"
I don't know the answer.

Unlike many of my classmates I was really good at the mathematical part of the exam questions and could straightforwardly solve them analytically. However, this took too much time! I bombed several important exams learning that "good enough" is an important attitude to have when solving engineering problems. I hated this intensely at the time. (Never give that Stalinist institution a dime till I die.) BUT. There's a reason I went into numerical analysis in graduate school. Which I loved then, turned into a transient career that I enjoyed immensely, and remember fondly.
I doubt this approach is feasible for non-engineering disciplines.
