What Is Final Exam Score with 1/3 Negative Marking

The Final Exam Score with 1/3 Negative Marking is the total points you earn after an exam subtracts points for wrong answers. In this system, you get full marks for a right answer. For a wrong answer, the exam takes away one-third of the marks assigned to that question. This score shows your true performance by penalizing random guessing.

How Final Exam Score with 1/3 Negative Marking Is Calculated

Formula

Final Score = (Correct × Marks) − (Wrong × Marks ÷ 3)

Where:

  • Correct = Number of correct answers
  • Wrong = Number of wrong answers
  • Marks = Marks awarded per correct answer

To find the final score, first multiply your correct answers by the marks for each question. This gives your positive raw score. Then, multiply your wrong answers by one-third of the marks per question. This gives your penalty. Finally, subtract the penalty from your positive raw score. The result is your net score.
