Combine assignment scores using total earned points divided by total possible points or explicit normalized weights. Each possible-point total must be positive.

Two-column rows are for total-points mode; weighted rows require three columns.
Assignment Grade Calculator validates method, rows: earned, possible [weight % for weighted mode] before applying the displayed equation. Two-column rows are for total-points mode; weighted rows require three columns.
Assignment Grade Calculator: points grade = Σearned / Σpossible × 100; weighted grade = Σ(earned/possible × weight) / Σweight × 100. Input definitions: mode = Method; rows = Rows: earned, possible [weight % for weighted mode]. Use the selected convention throughout the calculation.
Assignment Grade Calculator baseline input: Method: Total points; Rows: earned, possible [weight % for weighted mode]: 18 20 / 45 50. Output: Grade = 90 %; Points earned = 63; Points possible = 70. Substitute these values into the displayed equation to reproduce the result.

Understand the calculation
Weighted rows contain earned points, possible points and a weight. A 9/10 assignment weighted 20 and a 35/50 assignment weighted 80 give 90×0.2 + 70×0.8 = 74%. In total-points mode the same scores give 44/60 instead. Switching methods changes the denominator and the required number of columns; neither method is universally the school’s rule.
points grade = Σearned / Σpossible × 100; weighted grade = Σ(earned/possible × weight) / Σweight × 100
