SUMMARY

The final grade calculation discussed involves a weighted average based on percentages rather than points. The final exam accounts for 20% of the overall grade, while the coursework prior to the final constitutes 80%. The calculation performed was 0.8 multiplied by the course percentage (92%) resulting in 73.6, and 0.2 multiplied by the final exam score (88%) resulting in 17.6. Adding these results yields a final grade of 91.2, confirming the accuracy of the calculation.

my instructor has everything in percentages not points. the final was 20% of the overall grade. up until the final (80% of the course) i had a 92%. and i received an 88% on the final exam. so what i did was 0.8*92=73.6 and then i did 0.2*88=17.6. i then added the two and i got 91.something. did i calculate my final grade right?
