Question

A student of the author earned grades of 92, 83, 77, 84, and 82 on herfive regular tests. She earned grades of 88 on the final exam and 95 on her class projects. Hercombined homework grade was 77. The five regular tests count for 60% of the final grade, thefinal exam counts for 10%, the project counts for 15%, and homework counts for 15%.What is her weighted mean grade? What letter grade did she earn? (A, B, C, D, or F)

Answer 1

The class is weighted as follows:

60% Regular Tests

10% Final Exam

15% Project

15% Homework

The total weighted points possible for the class are as follows:

(100+100+100+100+100)*.6 + 100*.1 + 100*.15 + 100*.15 = 340

To calculate her individual final weighted grade we plug in her scores for each category and complete the following computation:

(92+83+77+84+82)*.6 + 88*.1 + 95*.15 + 77*.15 = 285.4

So her weighted grade percent would be 285.4/340 = 83.9% which is a B.
