Some high schools, to reflect the varying skill required for different course levels, will give higher numerical grades for difficult courses, often referred to as a weighted GPA. For example, two common conversion systems used in honors and Advanced Placement courses are: A = 5 or 4.5; B = 4 or 3.5 [5] C = 3 or 2.5; D = 2 or 1.5; F = 0 [19]
Grading in education is the application of standardized measurements to evaluate different levels of student achievement in a course. Grades can be expressed as letters (usually A to F), as a range (for example, 1 to 6), percentages, or as numbers out of a possible total (often out of 100).
When treating the weights as constants, and having a sample of n observations from uncorrelated random variables, all with the same variance and expectation (as is the case for i.i.d random variables), then the variance of the weighted mean can be estimated as the multiplication of the unweighted variance by Kish's design effect (see proof):
In a handful of states, GPA scales can go above 4.0. The percentage needed in any given course to achieve a certain grade and the assignment of GPA point values varies from school to school, and sometimes between instructors within a given school. The most common grading scales for normal courses and honors/Advanced Placement courses are as ...

Class rank is a measure of how a student's performance compares to other students in their class. It is commonly also expressed as a percentile . For instance, a student may have a GPA better than 750 of their classmates in a graduating class of 800.
GWA (general weighted average; similar to GPA) is a representation (often numerical) of the overall scholastic standing of students used for evaluation. GWA is based on the grades in all subjects taken at a particular level including subjects taken outside of the curriculum.
Weighted means are commonly used in statistics to compensate for the presence of bias.For a quantity measured multiple independent times with variance, the best estimate of the signal is obtained by averaging all the measurements with weight = /, and the resulting variance is smaller than each of the independent measurements = /.
