Create a weighted scoring model to determine grades for a course. Final grades are based on three exams worth 20%, 15%, and 25%, respectively; homework is worth 15%; and a group project is worth 25%. Enter scores for three students. Assume Student 1 earns 100% (or 100) on every item. Assume Student 2 earns 70% on each of the exams, 80% on the homework, and 95% on the group project. Assume Student 3 earns 90% on Exam 1, 80% on Exam 2, 75% on Exam 3, 80% on the homework, and 70% on the group project. You can use the weighted scoring model template, create your own spreadsheet, or make the matrix by hand.
