N'ihe banyere calculator a
A test score calculator converts the number of questions you got right out of the total into a percentage and a letter grade. Enter how many you answered correctly, or switch to entering how many you got wrong and it works out the rest. If wrong answers carry a penalty — some standardized exams deduct a fraction of a point to discourage guessing — set the points lost per wrong answer under advanced options; otherwise every wrong or blank question simply scores zero.
Worked example: 18 correct out of 20 is 18 ÷ 20 × 100 = 90%, an A-. If instead a quarter-point penalty applied to the 2 wrong answers, the raw score would be 18 − 0.25×2 = 17.5, giving 17.5 ÷ 20 = 87.5%, a B+.
A reference table shows exactly where each percentage falls on the letter scale. Teachers use it to grade quizzes and set curves, and students use it to check a score before results are posted or to see how many more questions they need right to reach the next grade.
