To calculate your overall grade, you will need to know the weighting of each assignment or exam in the class. Multiply each grade by its respective weighting and then add all of the results together. This will give you your total grade for the class.
Weighted grades take into account the difficulty or importance of each assignment or exam, while unweighted grades treat all assignments and exams equally. Weighted grades are often used to calculate a final grade, while unweighted grades are used to determine a student's progress throughout the course.
Each school or institution may have their own grading scale, but generally, a percentage of 90-100% is an A, 80-89% is a B, 70-79% is a C, 60-69% is a D, and anything below 60% is an F.
It depends on the weighting of the final exam in the class. If the final exam has a high weighting, then it can significantly impact your overall grade. However, if the final exam has a low weighting, it may not have as much of an impact on your grade.
To calculate what grade you need on the final exam, you will need to know the weight of the final exam in the class and the current grades you have in the class. Subtract your current grade from the grade you want to achieve, then divide that number by the weighting of the final exam. This will give you the minimum grade you need to get on the final exam to achieve your desired overall grade.
