How do I convert my test score to a percentage?

Divide the number of points you earned by the total possible points, then multiply by 100. For example, if you scored 42 out of 50 points, your percentage is (42 ÷ 50) × 100 = 84%. This percentage can then be converted to a letter grade based on your grading scale.

What if questions have different point values?

Add up all the points you earned across all questions to get your total score. Then divide by the sum of all possible points. For example, if you got 8/10 on essay questions and 15/20 on multiple choice, your score is 23/30 total points, or 76.7%.

How does a typical grading scale work?

Common grading scales are: A (90-100%), B (80-89%), C (70-79%), D (60-69%), F (below 60%). However, scales vary by institution and instructor. Some use plus/minus grades with more granular ranges, while others may have different percentage cutoffs.

Should I count questions I left blank as wrong?

Yes, for percentage calculations, blank answers count as incorrect (0 points). If you answered 20 out of 25 questions and left 5 blank, your score is based on how many of those 20 you got correct out of 25 total, not out of 20 attempted.
