You are finishing a course with these components: Participation: 85% (worth 10% of final grade) Midterm exam: 78% (worth 30% of final grade) Projects: 92% (worth 20% of final grade) Final exam: 88% (worth 40% of final grade) What is your final grade? You could calculate it manually: (85 × 0.10) + (78 × 0.30) + (92 × 0.20) + (88 × 0.40) = 8.5 + 23.4 + 18.4 + 35.2 = 85.5 Or you could use a grade calculator to instantly show your final grade is 85.5% (a B).
