Weighted Grade

In terms of mathematics calculations, the weighted grade is equal to the sum of the product of the weights (w) in percent (%) times the grade (g), while when the grades are not in percent then it will divide by the sum of weight.

Formulas

Below are the two formulas for the manual calculation of weighted grade.

Formula 1: WG = g1×w1+ g2×w2+ g3×w3+…

When the grades are in points or hours then use the below formula.

Formula 2: WG = (g1×w1+ g2×w2+ g3×w3+…)/(w1+w2+w3…)

Examples

The following two examples will help you to clear your mind about the above formula.

Example 1

Chemistry course with a grade of 80 and a weight of 30%.

Physic course with a grade of 90 and a weight of 50%.

Biology course with a grade of 72 and a weight of 20%.

Solution: Now, put the values in the 2nd formula:

WG = g1×w1+ g2×w2+ g3×w3+…

= 80×30%+90×50%+72×20%

= 83.4 Answer

Example 2

3 points Chemistry course with a grade of 80.

5 points Physic course with a grade of 90.

2 points Biology course with a grade of 72.

Solution: Now, put the values in the 1st formula.

WG = (g1×w1+ g2×w2+ g3×w3+…)/(w1+w2+w3…)

= (80×3+90×5+72×2)/(3+5+2)

= 83.4 Answer

History

At the year of 1785, the students of Yale used “optimi, inferiore, and pejores” which means “highest, lower and worse”. The William & Mary students use No.1 and No.2 system, while at that time the Harvard university used grade numerical systems from 1 to 200. Later in the year of 1883, Harvard starts using the “Classes” system where the student divide in class i, ii, iii, iv, and v, while v class presents the fail student’s grade.
In 1887, the Mount Holyoke was the first college to use a grading scale with the letters A, B, C, D, and E while E presents the fails students. This system was similar to nowadays grade system, but they later re-introduce their system and add an F letter for the fail students.

Frequently Ask Questions

In order to remove this fear, weighted grades were invented. It can boost class rank, increase grade point averages and reward top students for taking advanced courses.

 

They discourage students from taking electives and appropriately challenging classes, according to some administrators at White Bear Lake Area High School.

If a professor decides to increase or decrease the workload based on any group of students, weighted grades make that easy. In a scenario where grades are weighted by category and the number of assignments in a category changes, no changes to the course points or syllabus would be necessary.

It represents how many advanced classes you’ve taken, and your performance in them. Weighted GPA is important and matter more for extremely competitive schools.
