How to Calculate Your Final Course Grade

As you are ending your first semester of high school at Chatham Charter, we want to be sure you are fully aware of how a final grade is calculated for each of your courses.  Below is a step by step explanation for how this occurs:

Step 1: There are two grading periods per semester and a final exam.  Each grading period, your grade is worth 37.5% of your final grade.  Your final exam is worth 25% of your final grade.  Adding 37.5 + 37.5 + 25 = 100%, which is the total amount of your final grade.

Step 2: Calculating your final grade.  Let’s say you earned a 92 the first nine weeks, a 94 the second nine weeks and an 88 on the final exam.  Here is how the computer will calculate your final grade:

            First Nine Weeks                    Second Nine Weeks                    Final Exam

                        .375 (37.5%)                           .375                                         .25 (25%)

                      X  92                                       X  94                                    X 88

                        34.5                                      35.25                                         22

Step 3: If we total the points you earned in the first and second nine weeks with the points earned for your final exam, you will get your final grade for the course:

                                               34.5 + 35.25 + 22 = 91.75

Step 4: The final grade for this course is 91.75, which would round to 92.  This would give you a B in the course.

Step 5: If you want to keep up with your GPA, a B is worth 3 points.  If it is an honors course, you would receive a +1, so a B would then be worth 4 points.

If you have any questions about how your grades are calculated, please do not hesitate to ask your teachers, Ms. Liles, or an administrator.  Good luck on your exams!!!
