How to Use This Calculator

1

Enter your current grade

This is your grade in the class before the final exam. Check your school's gradebook for the most accurate number.

2

Enter the final's weight

This is the percentage of your total grade that the final exam is worth. Common weights are 20%, 25%, 30%, or 40%. Check your syllabus.

3

Enter your target grade

The grade you want to finish with in the course. For an A, enter 93. For a B+, enter 87. The calculator instantly shows what you need.

The Formula

Required Final Score = (Target − Current × (1 − Weight)) ÷ Weight

Where "Weight" is your final exam weight as a decimal (e.g., 30% = 0.30). This formula works for any course at any school.

Finals Week Triage Strategy

When finals week approaches, all study hours are not created equal. Use the concept of triage to maximize your Cumulative GPA.

  • 1
    The "Safe" Classes: If you calculate that you only need a 30% on your final to keep an A, stop studying for that class. Review your notes once, take the exam, and accept the A. Your time is better spent elsewhere.
  • 2
    The "Impossible" Classes: If you need a 115% on the final to bump your grade from a B to an A, and you're safely above a C threshold, accept the B. Don't waste 20 hours studying for a miracle that mathematically cannot happen.
  • 3
    The "Borderline" Classes: This is where you deploy all your effort. If you need an 88% to get an A, or a 75% to pass the class, this is where your study hours actually translate to GPA points. Focus on these exams above all else.

Frequently Asked Questions

The formula is: Required Exam Score = (Target Grade – (Current Grade × (1 – Exam Weight))) / Exam Weight. For example, if you want a 90% overall, have an 85% current grade, and the final is worth 20% (0.2), you need a 110% on the final to reach your goal.
Most courses use a 'weighted average' system. This means different assignments (homework, quizzes, midterms, finals) are assigned specific percentages of your total grade. To calculate it, you multiply each category score by its weight and add them together.
Your course Syllabus is the most reliable source for finding grading policies and the exact weight of your final exam. You can also sometimes find this breakdown in your student portal like Canvas or Blackboard.
If a final exam is worth 0%, or you are exempt from taking it, it does not affect your course grade at all. Your final overall grade is already mathematically determined by the assignments and assessments you completed during the term.
Knowing exactly what score you need on a final can drastically reduce test anxiety. It helps you set realistic goals and prioritize your study time, letting you focus heavily on the classes where a specific final exam score will actually change your letter grade.
