How to Figure Out What Grades I Need to Pass a Class

In many classes, teachers give assignments throughout the term in addition to a final exam. The final exam typically counts for a higher percentage of the grade in the class. Given the extra emphasis on the final, students often wonder how well they need to do on the final exam in order to pass the class. If you know your current grade, the lowest passing grade and the percentage that the final exam is worth, you can figure out the score you will need to achieve on the final exam.

Instructions

- 1
  Subtract the percentage that your final exam is worth from 100 to find the weight of your other assignments. For example, if your final is worth 30 percent of your grade, subtract 30 from 100 to find the rest of your assignments are worth 70 percent of your grade.
- 2
  Multiply the weight of your other assignments by your current grade in the class. In this example, if you have a 75 in the class, multiply 75 by 0.70 to get 52.5.
- 3
  Subtract the result from the lowest passing score. In this example, if the lowest passing score equals 68, subtract 52.5 from 68 to get 15.5.
- 4
  Divide the result by the percentage your final is worth to find the grade you need to get on your final to pass the class. Completing the example, divide 15.5 by 30 to get 0.5167, meaning you need a 51.67 percent or higher on your final to pass the class.
