What Test calculator does
The Test Calculator on RapidTables determines a test score and corresponding letter grade based on the number of questions and the count of wrong answers. Users receive a percentage grade, a letter grade, and a fractional grade (e.g., 85/100) instantly. The tool also includes a grade options table that shows how different wrong-answer counts translate into scores across various grading scales, allowing users to see the impact of each missed question before finalizing their results.
