A grade of no less than 90 is considered an "A."

To determine if a grade of no less than 90 is considered an "A," you need to check the grading scale or policy set by the specific institution or instructor. Different schools and instructors may have different grading systems. Here is a general explanation of how a grading scale might work:

1. Check the grading scale: Most educational institutions have a grading scale that determines the letter grade corresponding to a numerical score. It is usually provided in the syllabus or grading policy document for the course.

2. Find the grade range for "A": Look for the grading range associated with an "A" grade. For example, it might be mentioned that 90-100 is equivalent to an "A."

3. Determine if the grade meets the criterion: Compare the numerical score you have earned with the specified range for an "A" grade. If your score is equal to or higher than the minimum defined limit (in this case, 90 or higher), you have obtained an "A" grade.

It is important to note that this grading scale example is just one possibility, and the actual grading scale can differ from institution to institution. Therefore, it is crucial to refer to the specific grading policies and guidelines provided by your educational institution or instructor.
