The formula
grade = Σ(score × weight) ÷ Σ(weight)
Dividing by the weights entered gives your average on the work so far, so it works before the course is finished. Blank rows are ignored.
What to watch out for
Put each assignment, test or term in its own row, as a percentage score and its weight from the syllabus. Points work as weights too.
Frequently Asked Questions
How do I work out a weighted grade?
Multiply each score by its weight, add those up, and divide by the total weight. 85% at 20 and 78% at 30 gives 80.80%.
How do I work out a semester grade?
Enter each term and the exam as rows with the weights your school uses. Two quarters of 80% and 90% at 40% each, with a 70% exam at 20%, make 82.00%.
How do I work out a course grade?
The same way: one row for each graded category, using the weights in the syllabus. If a category holds several marks, average them first.
