How to use the Test Score Calculator
- Enter the total number of questions and the counts answered correctly and incorrectly.
- Open the advanced options when correct answers have unusual points or wrong answers carry a penalty.
- Review raw points, maximum points, percentage and unanswered questions.
- Set a target score to see the most questions you can get wrong and still reach it.
Raw-score arithmetic
The calculator uses the scoring values you enter:
raw points = correct × points per correct − wrong × penaltymaximum points = total questions × points per correctpercentage = raw points ÷ maximum pointsWhen there is no wrong-answer penalty and each correct response is worth one, this reduces to correct answers divided by total questions. Unanswered questions are shown separately and contribute no points.
How many you can miss
The target setting turns the same equation around. If every question you do not get wrong is answered correctly, each wrong answer costs its points plus the penalty, so:
most wrong = total × points each × (1 − target) ÷ (points each + penalty)most blank = total × (1 − target)Both are rounded down to whole questions. The blank count is shown only when a penalty makes it differ from the wrong count. The target is whatever you enter; the page does not assume a pass mark.
Not a scaled score
This is not a standardized-test converter. SAT, ACT, AP, IELTS and similar programs can use test-edition tables, section rules, equating or banding. Use the official score report or the exact table for that administration rather than treating a raw percentage as a scaled score.
With your numbers
- Most wrong answers for 70% = total × points each × (1 − target) ÷ (points each + penalty), rounded down = 12.
- Raw points = correct answers × points each − wrong answers × penalty = 40.5.
- Maximum points = 50.
- Test score = raw points ÷ maximum points = 81%.
Quick reference
This calculates the scoring rule you enter and does not convert to a standardized scaled score.
| Example | Test score |
|---|---|
| 42 correct, 6 wrong, 2 unanswered with penalty | 81% |
| 18 correct from 20 without penalty | 90% |
| All answers correct | 100% |
| Ten unanswered questions | 70% |
| Two points per correct answer | 80% |
| One-third wrong-answer penalty | 66.67% |
| How many can I miss for 90% of 20 | 90% |
| How many can I miss for 80% of 50 | 80% |
Common questions about the Test Score Calculator
- How are unanswered questions found?
- They are total questions minus correct and wrong answers. Ensure those answer counts do not exceed the test total.
- What is negative marking?
- It subtracts the entered penalty for each wrong answer. Leave the penalty at zero when wrong and unanswered responses receive no points.
- Can this calculate an SAT, ACT or AP scaled score?
- No. Standardized tests use edition-specific official conversion tables, not one permanent raw-score formula.
- How many questions can I get wrong and still pass?
- Enter the total and your target percentage. Without a penalty, the most you can miss is the share of the test below the target, rounded down: 20 questions at a 90% target allows 2. The page rounds down because one more wrong answer would take the score under the target.
- Why is the number I can miss smaller with negative marking?
- A wrong answer then costs twice: the points it would have earned and the penalty. Leaving a question blank costs only the points, so with a penalty the page also shows how many you could leave blank instead.
- Why can the score be negative?
- A sufficiently large wrong-answer penalty can reduce raw points below zero. Whether an exam floors scores at zero is part of its rules.
