I have a new idea for you.
My idea is as following.

I suggest publishing of the definite quantity of experimental pupil's mark book where all the necessary subjects would be marked by the mark "excellent" in corresponding column IN ADVANCE! Thus the pupils would start their first year of study at school with beforehand suggested feeling that there are no other "right" marks with the exception of "excellent" and would do their best to suit the aforesaid status of the excellent pupil.

So, what do you think about the rationality of the idea?
