This 2-hour training from April 2021 detailed how to set up and use a D2L points-based or weighted gradebook. There was Q&A at the end. Specifically, participants learned how to: 

• Create Categories and Grade Items.
• Distribute weights within a category and drop the lowest score.
• Create bonus items and work with extra credit.
• Enter grades and feedback.
• Connect and assess activities.
• Preview and release grades.
• Export and import grades.
• Switch to adjusted final grades.
