In some schools, primarily public high schools, weighted-grade systems give students a numerical advantage for grades earned in higher-level courses or more challenging learning experiences, such as honors courses, Advanced Placement courses, or International Baccalaureate courses.
For example, the weighted average of a list of numbers $x_1,\ldots,x_n$ with corresponding weights $w_1,\ldots,w_n$ is $${w_1\cdot x_1+w_2\cdot x_2+\ldots+w_n\cdot x_n\over w_1+w_2+\ldots+w_n}$$ Note that if the weights are all just $1$, then the weighted average is just a plain average.
