The STAAR test is given to all students in the state of Texas. The exact number of questions that you can miss depends on the test and the grade level.
To achieve a score of 70% on a 300-question test, you would need to answer 210 questions correctly. To find out how many questions you can miss, subtract the number of correct answers from the total number of questions: 300 - 210 = 90. Therefore, you can miss up to 90 questions on a 300-question test and still achieve a score of 70%.
Set up the ratio in this form: (number of correct answers / total number of questions) x 100 Since there are 42 questions total in a test, we have: (number of correct answers / 42) x 100 Whatever number of correct answers the student has on a test, you compute the grade for him/her. For instance, if you have all correct answers, then we have: 42/42 x 100 = 100%
You cannot know that. If you are told the total number of points for the test, you know (or count) the number of questions and you are told that each question is worth the same number of points then, and only then, each question is worth (total points/number of questions) points.
Fallow these steps to find out the percent of any test or homework assignment: 1. Divide the number you got by the number its out of. 2. Multiply that number by 100. And there you go your percentage. If you want to find your grade average than fallow these steps: 1. Add all your marks up from all your classes. 2. Divide them by the number of classes you have. 3. Multiply that by 100.
