The phrase "8 of 30" is commonly used in school assessments, exams, and quizzes to refer to a specific portion or percentage of the total questions or points available. When an instructor presents a test or quiz that consists of 30 questions, and a student answers 8 of those questions correctly, the student's performance can be described as being 8 out of 30.
This figure is often used to calculate a percentage score or grade. To determine the percentage, you divide the number of correct answers (8) by the total number of questions (30), and then multiply the resulting fraction by 100 to convert it into a percentage. In this case, (8/30) x 100 = 26.67%. This means that the student answered 26.67% of the questions correctly.
In some educational settings, a separate letter grade is assigned based on a curve. If the instructor uses a curve where 80% of the class scores 8 or higher on the test, then a student who scored 8 out of 30 would be assigned a letter grade of "F," which stands for "fail." In this case, the instructor used a curve that was more demanding than the usual grading scale, resulting in a lower percentage score for the student.
It is important to note that the meaning of "8 of 30" can vary depending on the context and the grading criteria set by the instructor or institution. Some instructors might use this phrase to indicate that a student has answered 80% of the questions correctly, while others might use it to mean that the student has performed at a satisfactory level.
Overall, the phrase "8 of 30" is a standardized way of referring to a specific percentage or part of a total, and it is widely understood across different educational contexts.
