If we had trouble following your instructions, it’s because they were written like this…

The project was not a difficult, much of which demonstrates ability to follow instructions. Because this project was worth 15% of your grade and the intent was for everyone in the group to participate and “sign-off” before it was submitted & although the instructions & guideline sheet (attached) states “points will be given as all or none for each area above”, no partial credit will be given, I did give partial credit (unless one of the criteria was omitted completely, in which case no credit was given).

Please, take pride in your writing. All of it.
