Expression: The 'mark distribution' in English and Urdu papers does not...

Hi

Could you please tell me if the following sentence is correct and natural?

The ‘mark distribution’ in English and Urdu papers does not seem very much justified considering that a student aged 7+ is supposed to write creative writing covering 40% of the paper in one and a half hours.

I would consider ‘justified’ a non-gradable adjective.
‘Write creative writing’ is not the best style.
I would think it is the ‘relative mark distributions…do not’.

Many, many thanks, Mister Micawber!

Could you please help me repharase the sentences?

Tom
