To calculate your final grade, you need to consider the weight of your exam and the current grade.
The current grade is 77% and its weight is 80%. The exam's weight is 20%.
To calculate your final grade:
(0.80 * 77) + (0.20 * 78) = 61.6 + 15.6 = 77.2
Therefore, scoring 78% on the exam would result in a final grade of approximately 77.2%.
