Gentle suggestion: The "How Marks are Calculated" section has an equation that, while helpful to those who remember algebra, prompted me to skip the section (since it's Greek to me).
The important advice to *use a zero in each row* should perhaps be put at the top of this section. As it stands, it's buried at the bottom. If other teachers skip like me, they'll miss it. Less likely, again, if it's on top of the section.
Or better still, given its own section in "Assigning Point Values in the Rubric" or something.
