Class grade calculator

How do you calculate a weighted grade?

In a weighted class, each category counts for its share of the course. Multiply each category's average by its weight to get its course points, then add them up.

Grade so far = total course points ÷ graded weight × 100

In the example, homework at 92% with a 40% weight adds 36.8 course points. Tests at 85% add 34, and the final project at 78% with a 20% weight adds 15.6. Together they make 86.4%.

If your gradebook uses points, choose points. Add earned points and possible points separately, then divide. A plain average only fits scores that count equally.

What if some work is still ungraded?

For example, 80% at 60% weight with the remaining 40% blank gives an 80% current grade and 48 course points. If that blank becomes zero, the course grade becomes 48%. Carry the current grade into the final grade calculator when the exam is all that remains.

Leave its score blank and keep its weight. Your current average leaves that work out until you enter a score. A zero is a real score, so enter it when the work earned no credit.

To try a future score, enter it and open the row's ⋯ menu to mark it as a what-if score. You will see the projection separately from your current grade. The remaining range assumes future scores between zero and full credit.

In points mode, extra credit adds earned points without adding possible points. Dropping a score removes both. For a letter grade, use the rounding rule your syllabus gives you.

Can I import my grades instead of typing them?

Yes. Under the calculator, open “Import grades from a spreadsheet or CSV” and paste your gradebook’s rows, one row per assignment, or open a CSV file. The calculator finds the assignment, category, score and points possible columns by their names, and shows how it read every row before you use them.

Scores can be written as 18/20, 90%, a letter such as B+, or a number beside a points possible column. A blank or a dash means not graded yet, and EX or Excused is left out; a zero counts. Work marked Missing is left out unless you choose to count it as 0. A row named Total is skipped, so nothing counts twice. Without categories, work not graded yet comes in as a blank row, ready for a what-if score.

With a category column, each category becomes one weighted row: type its weight from your syllabus, and choose whether the points inside it are added up or every assignment counts the same.
