I have couple of weeks left of my semester, my grade is a 72% and my exmans are worth 30% is kg possible to finish with an 80%? What do I need to get on my exam?
To determine the grade you need to achieve on your final exam in order to finish with an 80% overall, you need to consider the weightage of your exams and the current percentage you have in the class.
Since your exams are worth 30% of your overall grade and you currently have a 72%, the remaining 70% of your grade holds a 28% weightage.
Let's assume you want to achieve an 80% or higher overall grade in the class. You would need your final exam to contribute enough points to bring your overall percentage up to 80%.
To calculate the required exam grade, you can set up the following equation:
(72% * 0.28) + (exam grade * 0.30) = 80%
0.2016 + (exam grade * 0.30) = 80%
exam grade * 0.30 = 80% - 0.2016
exam grade * 0.30 = 79.7984
exam grade = 79.7984 / 0.30
exam grade = 265.9947
Therefore, you would need to score approximately 266% on your final exam to finish with an 80% overall grade, which is not possible.
Since it is not possible to achieve an 80% with the given exam weightage, you may want to consider other ways to improve your grade, such as focusing on homework, projects, or any other assignments that can help improve your overall percentage.
