I remember we did it. Though not that strictly. Just some program and eventually got a grade for it based on usually grading system. I would have never passed so strict requirements, well i never have passed so strict requirements anyway.

Our native language teacher had similar strict requirements. I didn't pass a single exam that year, regardless of how many times i tried or for how long i studied.

So I'm completely with you, screw that type of teachers. Making mistakes is human.
