Percentile ranks are not on an equal-interval scale; that is, the difference between any two scores is not the same as between any other two scores whose difference in percentile ranks is the same. For example, 50 − 25 = 25 is not the same distance as 60 − 35 = 25 because of the bell-curve shape of the distribution. Some percentile ranks ...
In statistics, a k-th percentile, also known as percentile score or centile, is a score below which a given percentage k of scores in its frequency distribution falls ("exclusive" definition) or a score at or below which a given percentage falls ("inclusive" definition); i.e. a score in the k-th percentile would be above approximately k% of all scores in its set.
The first quartile (Q 1) is defined as the 25th percentile where lowest 25% data is below this point. It is also known as the lower quartile. The second quartile (Q 2) is the median of a data set; thus 50% of the data lies below this point. The third quartile (Q 3) is the 75th percentile where
Beginning in the Fall of 2024, first-year courses on Grading Option A, other than Legal Profession I and II, shall be subject to the following grade distribution: 5-25% of the class shall receive A+, A, A-, or B+ grades; 35-65% of the class shall receive B, B-, C+, or C grades; 15-40% of the class shall receive C-, D+, D, or F grades.

Colleges often use class rank as a factor in college admissions, although because of differences in grading standards between schools, admissions officers have begun to attach less weight to this factor, both for granting admission, and for awarding scholarships.
The top grade, A, is given here for performance that exceeds the mean by more than 1.5 standard deviations, a B for performance between 0.5 and 1.5 standard deviations above the mean, and so on. [17] Regardless of the absolute performance of the students, the best score in the group receives a top grade and the worst score receives a failing grade.
For the first time since 2019, the N.C. Department of Public Instruction released A through F grades for North Carolina schools.
The ECTS system initially divided students between pass and fail groups and then assessed the performance of these two groups separately. Those obtaining passing grades were divided into five subgroups: the best 10% are awarded an A grade, the next 25% a B grade, the following 30% a C, the following 25% a D and the final 10% an E.
