How Semester Grades are Calculated at JTHS

At Joliet West, my semester grade is worth 80% of my overall grade and my final exam is worth 20% of my overall grade.

Mathematically, it would look like this -


.80(semester grade) + .20(final exam grade) = Semester Grade.


If I received a 89% in Algebra and earned a 75% on my final exam, I would calculate my grade like this-


.80(89) + .20(75) = ?

71.2 + 15 = 86.2


This means I would earn an 86.2% in Algebra for the semester.
