You are teaching an introductory science course in which users are graded on four labs, their participation in discussion topics, and a final examination. You allow users to drop their lowest grade on a lab. You also provide bonus grades to users who act as moderators for discussion topics. If a user does not submit a lab, you leave it ungraded and treat ungraded items as a grade of 0.
You set up grade items and a Labs category with the following properties:
|

You release the calculated final grade to Frank. It is calculated as follows:
Grade item |
Calculation |
Lab 1 |
= Dropped Note: Dropped grade items are not included in calculations; grades are calculated as if the item does not exist. |
Lab 2 |
= 8/10*25/(25+25+25)*100 = 26.67% towards the category = 26.67*.5 = 13.33% towards the final grade Note: Lab 1 is worth 33.33% of the Labs category even though it is assigned a weight of 25%. This is because the lowest lab grade is dropped and there are only three labs contributing to the category. |
Lab 3 |
= 0/10*25/(25+25+25)*100 = 0% towards the category = 0*.5 = 0% towards the final grade See the note for Lab 1. |
Lab 4 |
= 7/10*25/(25+25+25)*100 = 23.33% towards the category = 23.33*.5 = 11.67% towards the final grade See the note for Lab 1. |
Discussions |
= 8/10*10 = 8% towards the final grade |
Moderator |
= 3/5*5 = 3% on top of the final grade Note: Bonus items are added to the final grade after other calculations. Do not include a bonus item’s weight in your total when balancing your grade book. |

= 71/100*40 = 28.4% towards the final grade |

= 13.33+11.67+8+3+28.4 = 64.4% |
