Math Problem Statement
A student has the following marks: Projects - 65%, Tests - 85%, and Quizzes - 74%.
If Projects are worth 25%, Tests 60% and Quizzes are worth 15%, what is their current grade? Type your answer in the space below and show all of your work.
Solution
To calculate the student's current grade, we use a weighted average formula:
Formula:
Given:
- Projects Grade:
- Tests Grade:
- Quizzes Grade:
- Weights:
- Projects = or
- Tests = or
- Quizzes = or
Calculation:
-
Weight for Projects:
-
Weight for Tests:
-
Weight for Quizzes:
-
Total Grade:
Final Answer:
The student's current grade is 78.35%.

- What is the importance of weights in calculating a grade?
- How would the grade change if the weights for Tests and Projects were swapped?
- What is the difference between weighted and unweighted averages in this context?
- How does one determine the weights in a grading system?
- Could a lower score in Quizzes be offset by a higher weight for Tests? How?
Tip: Always double-check weights to ensure they sum to 100% when calculating weighted averages.
