How to combine exams into one weighted result

Most schools decide the year's result from more than one exam. The midterm might count for 40 percent and the final for 60, or a college might give continuous assessment 30 percent. Usually someone copies each exam's percentages into a spreadsheet at the end of the year and works out the final figure by hand. SkoolBro can now do that from the marks it already has.

What a weighted result is

A weighted result belongs to one school year. It lists two or more exams of that year, each with a share in percent, and the shares add up to 100. For every student, SkoolBro takes each exam's percentage, multiplies it by the exam's share and adds them up. Subjects are combined the same way, so you get a weighted figure for Mathematics, English and the rest, as well as the overall one.

Take Ada at Riverside Grammar, a fictional school. She scored 70 percent in the midterm and 80 percent in the final. With the midterm at 40 percent and the final at 60 percent, her result is 0.4 × 70 + 0.6 × 80, which is 76 percent. In Mathematics she scored 80 and then 90, so her weighted Mathematics figure is 86.

Step 1: finish the exams

A weighted result reads the marks of its exams, so set up the exams and enter marks as usual. You can add the weighted result while marking is still going on and watch the figures fill in. Families only see it once every exam in it is published.

Step 2: add the weighted result

1. Open Exams and choose the Weighted results tab.
2. Pick the school year and select Add weighted result.
3. Give it a name, such as "Annual result 2026-27", and choose the grading scale. The grade for each student and subject comes from this scale.
4. Tick the exams that count. SkoolBro suggests equal shares. Change them to your rule, for example 40 and 60. The total shows under the list and must reach 100.
5. Save. The weighted result opens on its own page.

Step 3: check the class results

Choose a class at the top of the page. The table shows, for each student:

• the percentage in each exam, with the exam's share in the column heading,
• the weighted percentage and grade for each subject,
• the weighted overall percentage, grade, pass or fail, and position in the class.

Students with equal percentages share a position, and the next position is skipped, as on the normal results page. You can sort the table by roll number or by position, and print it.

A student counts as passed when they passed every exam in the weighted result. If an exam has no marks for a student, that exam counts as 0, the row says marks are missing, and the student does not pass until the marks are in. This makes gaps easy to find before you publish.

If a class did not sit one of the exams, for example a new section that joined after the midterm, the shares are spread over the exams it sat, and the page says so.

Step 4: publish it to families

Select Publish on the weighted result page. SkoolBro checks that every exam in it is published first. Once it is published, parents and students see it at the top of the Results tab in the family portal: the overall percentage, grade, position and result, then each exam with its share, then each subject.

To change the shares or the exams later, unpublish it, make the change and publish it again. If someone unpublishes one of the exams to correct marks, the weighted result disappears from the portal until that exam is published again, so families never see figures built on marks that are being changed.

Examples of rules you can set up

• A school year: first term 25 percent, midterm 25 percent, final 50 percent.
• A college semester: quizzes and assignments set up as one exam at 30 percent, the final at 70 percent.
• A training institute: continuous assessment 40 percent, final assessment 60 percent, per module.

Each exam can be part of more than one weighted result. You might keep a "Term 1 result" and an "Annual result" side by side. An exam that is part of a weighted result cannot be deleted, so the figures do not change by accident.

What is not built yet

There is no printed report card for a weighted result yet, and families get no notice when one is published. Each exam's own report card still works as before. A grade point average across several semesters is not built either. For the rest of the exam process, see making an exam date sheet and examinations and results.

Questions

Do the shares have to add up to 100?

Yes. SkoolBro refuses the weighted result until they do, and shows the total while you type. Two exams at 40% and 60% work, and so do three at 20%, 30% and 50%.

What happens if a student missed one of the exams?

The missing exam counts as 0, and the student's row is marked as missing marks so the office can check it. A student marked absent in a paper gets 0 for that paper in the usual way.

What if one class did not sit every exam?

The shares are spread over the exams that class sat. If a class sat only the final, the final is its whole result. The results page says which share each exam has for that class.

Can I change the shares after publishing?

Unpublish the weighted result first, change it, then publish it again. Families stop seeing it while it is unpublished.

Is there a printed report card for the weighted result?

Not yet. The weighted result page prints as a class table, and families see their child's figures in the portal. Each exam still has its own report card.
