- Current grade = 78
- Weight of the final = 30
- Target overall grade = 85
- w = 30 / 100 = 0.3
- Score needed on the final = 0.3 > 0 ? (85 - 78*(1 - 0.3)) / 0.3 : 0 = 101.333
- Best possible overall grade = 78*(1 - 0.3) + 100*0.3 = 84.6
- Worst possible overall grade = 78*(1 - 0.3) = 54.6
- Within reach = 101.333 <= 100 ? 1 : 0 = 0
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.
