You want (at least) a % in the class. Tests are worth % of your grade. You have taken tests already. Your test average is %. The final is worth tests. Calculate what I need on the final ✕ Question: There are 2+ parts in my final. What do I have to get on them? If your final has multiple parts and you’ve finished some of them, then you can calculate what you need on the remaining parts. Your current grade should not include any part of your final. Your current grade is %. You want (at least) a % in the class. Your final is worth % of your grade. You have parts to your final. You have taken part(s) already. Your 1st part is worth points. Your 2nd part is worth points. Your 3rd part is worth points. Your 4th part is worth points. Your 5th part is worth points. Your 6th part is worth points. Your 7th part is worth points. Your 8th part is worth points. On part 1, you got points. On part 2, you got points. On part 3, you got points. On part 4, you got points. On part 5, you got points. On part 6, you got points. On part 7, you got points. Calculate what I need on the rest of the final ✕ Question: My class has a point system. How much is the final worth? You can calculate how much your final is worth by dividing the number of points in your final by the total number of points. Including the final, there are points possible.

How does this work?

Most class grades are made up of several categories: homework, classwork, tests/quizzes, and the final exam. Usually, each category is worth a percentage of your overall grade. But because your final exam isn't scored until the very end, it isn't included when calculating your current overall grade. Instead, all the other categories are scaled up to consume the weight reserved for the final exam. Therefore, you can calculate the minimum grade you need to score on the final exam using the formula:

Required = (Goal − Current × (100% − Final Weight)) / Final Weight

See the formula sheet for an explanation of this formula and other formulas used in this calculator. It's not rocket science, it's just math! You could, of course, do this on any calculator, but you're here on RogerHub because it's cool. (:
