Step-by-Step Guide to Calculate Your Final Grade

Step 1: Gather Your Grade Information

Collect all your assignment scores and their corresponding weights. Most courses provide a syllabus that outlines the grading breakdown. For example:

Homework: 20% of final grade
Quizzes: 30% of final grade
Midterm Exam: 25% of final grade
Final Exam: 25% of final grade

Step 2: Convert Scores to Percentages

If your scores aren't already percentages, convert them. Formula: (Points Earned ÷ Total Points) × 100

            Example: You scored 85 out of 100 on a test

            Percentage = (85 ÷ 100) × 100 = 85%

Step 3: Calculate Weighted Components

Multiply each component's percentage by its weight (as a decimal). Formula: Component Grade × Component Weight

            Example:

            Homework: 90% × 0.20 = 18.0 points

            Quizzes: 85% × 0.30 = 25.5 points

            Midterm: 88% × 0.25 = 22.0 points

Step 4: Sum All Weighted Scores

Add all weighted component scores together to get your current weighted average.

            Current Weighted Average = 18.0 + 25.5 + 22.0 = 65.5%
        

Step 5: Calculate Final Grade (After Final Exam)

Once you complete your final exam, add its weighted score to your current average.

            Example: Final Exam = 92% × 0.25 = 23.0 points

            Final Grade = 65.5 + 23.0 = 88.5%

Scenario: Calculating Final Grade for Math Course

You're taking a math course with the following grading breakdown:

Component	Your Score	Weight	Weighted Points
Homework	85%	40%	34.0
Midterm	90%	30%	27.0
Final Exam	88%	30%	26.4
Total	-	100%	87.4%

Your final grade is 87.4%, which corresponds to a B+ letter grade.

What Grade Do I Need on My Final Exam?

One of the most common questions students ask is: "What grade do I need on my final exam to achieve my target grade?" Here's how to calculate it:

Formula for Required Final Exam Score

Required Final Score = (Target Grade - Current Weighted Average) ÷ Final Exam Weight

            Example:

            Current weighted average: 85% (from 70% of course)

            Target final grade: 90%

            Final exam weight: 30%

            Required = (90 - 85) ÷ 0.30 = 16.67 points

            You need approximately 96.67% on your final exam
