This sounds interesting. Personally, I think the education system needs tearing up by the roots and a total rethink. The obsession with exams is insane. The only test that ought to be done under exam conditions (that I can think of) is a driving test. Do journalists write articles under exam conditions? Do scientists prepare papers for peer review under exam conditions? Do novelists write books under exam conditions? It's insane.

All that said, whilst this idiotic system exists, a part of me is pleased that people like Michaela exist, in a tough love sort of way. I don't necessarily approve of everything she does, but as you say, the results are undeniable.
