The same way you grade any test - you add up how many questions the student got correct and then divide that by the total number of questions. In order to change that into percentage, you then multiply that number by 100.
For example, if someone got 92 out of 110 questions right, their score would be 92/100 = 0.836 x 100 = 83.6 percent.

For 100 questions you get 1 point per question; for 110 questions it is 1/1.1 = 0.9 points each question
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.
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%
If there are 85 questions, a passing grade of 80% would be 68 correct answers.
First, take 18/32, which is about .563. Then multiply by 100, which is 56.3. So the grade is about 56.3%.
well each question is worth 3.3333333 points so multiply how many you got right by 3.333333 and that's your grade
