Our organization has a program that uses a unique grading structure. I will do my best to explain it.

The course has several exams and a final. Students are required to get a 77% or higher on their exams before other course work can be included and their course total calculated. The number of exams varies from course to course. The course also uses weightings for exams, a final exam, and other course work.

Example:

- Exam Totals = 68%
- Exams = 48% weighting (spread equally over the number of exams in the course)
- Final Exam = 20% weighting (1 item)

- Final Paper = 10% (2 items)
- Certification = 10% (1 item)
- Participation and Attendance = 12% (many items)

Our current setup uses the following arrangement:

The course has 3 categories and a single item (Exam Totals, Final Paper, Participation and Attendance, and the Certification). All together these 4 items equal 100% of the course grade. In our previous LMS we have created a parent category called Exam Totals. This category contains a sub-category called Exams and a single gradable item called Final Exam. We have given the parent category (Exam Totals) a weighting of 68%, the sub-category Exams a weighting of 48%, and the single item Final Exam a weight of 20%. The remaining 3 items are weighted based upon the information above.

We would like the students to know their Exam Totals value (i.e. have they earned the 77% necessary in their Exam Totals to be eligible to pass the course) and then their final grade (which includes everything).

I can create a category for each weighting (48%, 20%, 10%, 10%, 12%), but I cannot see a way to combine the 48% and 20% in order to calculate a value.

Is there a way we can configure the gradebook to show 2 different aggregations to the students? One that contains only specific items using a weighting and another one that contains all the gradable activities in the course?

Thank you for your advice and input.

Jon Krasnichan,

You cannot natively combine the 48% and 20% into one category. There are some other discussions that have asked for similar thing and reading them may provide some insight into the current state. But the short answer is

noand you can skip the discussions and skip to the work-arounds I provide below. Of course, reading them might provide a different approach that you like better. Here are the discussions: Different Weighting to different quizzes , Weighting Grades Proportionally within an Assignment Group , More complex rules for assignment groups , and Assessment weighting by course .I got a little lost in there, but I think you're saying you need the 77% in all exams, both regular and the final. And that you want students to be able to see their grades as they go.

In this case, you can just combine them into one area worth 68% of the final grade. Then weight the regular exams and the final exam based on how many there are. Each course may have a different point value depending on how many exams there are going to be in that course. If your exams are based off of Canvas quizzes, things may be a bit harder.

## Method 1: Weight Regular Exams, Keep Final at 20%

For example, if you have a 3 regular exams and a final, then 48%/3 = 16% and the final is 20%. So make the regular exams worth 16 points and the final worth 20%. Or you could use any multiple of that - 32, 32, 32, and 40.

If you had 4 exams, then 48%/4 = 12%, so make the exams 12, 12, 12, 12, and the final 20.

If you had 5 exams, then 48%/5 = 9.6%, so have 5 exams worth 9.6 points each and the final worth 20 points.

That approach has the benefit of letting students see exactly how much of their final grade they've earned, but it gets away from displaying things as a percent. Thankfully, the student's grade page shows the percent in a category, so they could see if they have the 77% or not.

## Method 2: Keep Regular Exams at 100%, Weight Final

Now, if you are more worried about the students seeing their scores as a percent, then you can take a different approach. In this case, you would weight each regular exam worth 100 and then weight the final to make it worth 20%.

So, if you had 3 regular exams worth 100 points each, you would have 300 points possible. That needs to be 48% of the grade and the final 20% of the grade. The question is to figure out how much the final should be. To answer this question, you need say that 300 is 48% out of 68% = 48/68 = 12/17 = 70.58823529% of the "Exam Totals" grade. The final exam is 20% out of 68% = 20/68 = 5/17 = 29.41176471% of the "Exam Totals" grade.

If 300 points is 12/17 of the "exam totals" grade, then the exam totals grade is 300/(12/17) = 300*17/12 = 425 points. Since the regular exams already account for 300 points, the final should be 125 points. By the way, that's 5/12 of the 300.

If you had 4 regular exams worth 100 points each, then you would have 400 points of regular exams. 400*17/12 = 566.66666 points. Take away the 400 points in regular exams and you would have 166.666666 points for the final. By the way, that's 5/12 of the 400.

After you do the calculations a couple of times, you start to wonder if you could simplify the algebra or come up with an exam? The answer is yes.

If you have n exams worth 100 points, then you should make the final exam worth 100n*5/12 = 500n/12.

2 exams: 500*2/12 = 1000/12 = 83.33 points for the final

3 exams: 500*3/12 = 1500/12 = 125 points for the final

4 exams: 500*4/12 = 2000/12 = 166.67 points for the final

5 exams: 500*5/12 = 2500/12 = 208.33 points for the final

6 exams: 500*6/12 = 3000/12 = 250 points for the final.

You could even divide 500/12 = 125/3 = 41.6666666 and then multiply that by the number of exams. But the 500/12 makes for nice numbers that show you add 500 points for each regular exam and then divide it by 12.

I think I like the second method better. Students see 100 points for each exam all the way until the end so they're not paying attention to the fact that the final is some weird number until the end of the term.
