how to calculate your grade with weighted assignments

 To calculate your grade with weighted assignments, you'll need to know the weight of each assignment category and your scores in those categories. Here's a step-by-step guide:

  1. List the Categories and Weights: Write down each category (like exams, quizzes, homework, etc.) and its corresponding weight as a percentage. Ensure that the total weight sums up to 100%.

  2. Record Your Scores: Write down your scores in each category. If a category has multiple assignments (like several quizzes), calculate the average score for that category.

  3. Convert Weights to Decimals: Convert the percentage weights to decimal form by dividing them by 100. For example, a weight of 25% becomes 0.25.

  4. Multiply Scores by Weights: Multiply your score in each category by its corresponding decimal weight.

  5. Sum the Weighted Scores: Add up all the weighted scores. This sum is your weighted average score.

  6. Determine Your Grade: Compare your weighted average score to the grading scale provided by your instructor or institution.

Here's an example calculation:

  • Assume your grades are as follows: Exams 90% (weight 50%), Quizzes 80% (weight 20%), Homework 95% (weight 30%).
  • Convert weights to decimals: Exams 0.50, Quizzes 0.20, Homework 0.30.
  • Multiply scores by weights: Exams = 90 * 0.50 = 45, Quizzes = 80 * 0.20 = 16, Homework = 95 * 0.30 = 28.5.
  • Sum the weighted scores: 45 + 16 + 28.5 = 89.5.
  • Your weighted average score is 89.5.

Remember, different schools or courses may have different grading scales, so it's important to use the specific scale provided by your instructor or institution to determine your final grade.
