Hi Robert:
I cannot comment directly to your question. I can say that grades are just points. What we want to achieve is learning and skills that prepare students for work. Perhaps coupling a weaker student with a brighter student as partners will assist the weaker student learn what's needed. Students like to help their classmates if they're able.
Failure is when the student gives up. Until that point, they'll always have a chance.
