Think about it this way: If you have 50 questions, each one would be worth 2 points in order to make a grade of 100. That means you can miss 5 questions before you get down to 90 (5 x 2 = 10).
To achieve a score of 70% on a 200-question test, you would need to answer 140 questions correctly. This means you can afford to miss 60 questions and still achieve a 70% score.
In order to score 80% on a test with 30 questions, you must give 6 wrong answers. You can do it!
To achieve a score of 90% on a 56-question test, you would need to answer 90% of the questions correctly, which is 50.4 questions. Since you cannot answer a fraction of a question, you would need to answer at least 51 questions correctly. Therefore, you can afford to miss 56 - 51 = 5 questions and still achieve a 90% score on the test.
The answer will depend on the total score for the test and whether or not all the questions are score the same.
In order to score 95% or better, you must answer at least 76 questions correctly. We're hoping it's not a math test.
To score 80 percent on a 125-question test, you need to answer 100 questions correctly (since 80% of 125 is 100). Therefore, you can miss a maximum of 25 questions to achieve this score.
To achieve a score of 70 percent on a 25-question test, you need to answer at least 18 questions correctly (70% of 25 is 17.5, which rounds up to 18). This means you can miss a maximum of 7 questions (25 - 18 = 7). Therefore, you can miss 7 questions to still score 70 percent or above.
To score 70 percent on a 30-question driving test, you need to answer at least 21 questions correctly (70% of 30 is 21). Therefore, you can miss up to 9 questions (30 total questions minus 21 correct answers) to still achieve a passing score of 70 percent.
you can't answer the question if you don't know how many total questions there are
To achieve a score of 95 percent on a 100-question test, you can get a maximum of 5 questions wrong. This means you must answer at least 95 questions correctly, as 95 out of 100 equals 95 percent.
To achieve a score of 70 percent on a 10-question test, you need to answer at least 7 questions correctly. This means you can miss a maximum of 3 questions. Therefore, missing 3 questions would still allow you to meet the 70 percent threshold.
To achieve a score of 75 percent on a 15-question test, you can get a maximum of 3 questions wrong. This is because getting 75 percent means answering 75 percent of the questions correctly, which equates to answering 11.25 questions correctly. Since you can't answer a fraction of a question, you need to answer at least 12 questions correctly, allowing for 3 incorrect answers.
To achieve a score of 70% on a 200-question test, you would need to answer 140 questions correctly. This means you can afford to miss 60 questions and still achieve a 70% score.

To achieve an 80 percent score on a 27-question test, you would need to answer 80% of the questions correctly. This means you can get 20% of the questions wrong. To calculate the number of questions you can miss, multiply 27 by 0.20 (20%) to get 5.4. Since you can't have a fraction of a question, you would need to round down to 5 questions. Therefore, you can miss 5 questions out of 27 to achieve an 80 percent score.
To achieve 80 percent on a 40-question test, you need to answer at least 32 questions correctly (80% of 40 is 32). This means you can only get 8 questions wrong (40 - 32 = 8). Therefore, to score 80 percent, you can afford to miss a maximum of 8 questions.
