Formulas Used

Grade Needed on Remaining Work

needed_grade = (desired_grade - current_grade * current_weight / 100) / (remaining_weight / 100)

Weight of Remaining Work

remaining_weight_out = remaining_weight

Points Earned So Far

current_points = current_grade * current_weight / 100

How It Works

How to Calculate the Grade You Need

This determines the minimum grade on upcoming work to hit your target.

Formula

Needed Grade = (Desired Grade - Current Grade x Current Weight) / Remaining Weight

All weights are expressed as decimals (60% = 0.60).

Worked Example

You have an 82% with 60% of coursework done and want an 85% final grade.

current_grade = 82current_weight = 60desired_grade = 85
  1. 01Points earned so far: 82 x 0.60 = 49.2
  2. 02Points still needed: 85 - 49.2 = 35.8
  3. 03Remaining weight: 100% - 60% = 40%
  4. 04Grade needed: 35.8 / 0.40 = 89.5%
