Grade curving is defined by the distribution of the scores of all the pupils in the class. We take the square root of 75 which is about 8666 and multiply it by 10 giving them an 866 curved grade.

If the highest percentage grade in the class was 88 the difference is 12.
Use curves to add different levels of contrast to your image remap white and black levels tweak highlights and.

Method 2 - Use a flat-scale formula. A grading curve means the professor takes the top score or the second top score his choice and makes that a 100. The short answer is that the grading curve is required by College of Business administration.
They have good reasons for this. Method 3 - Use a bottom limit to define an F. If the top or bottom performing student exit the program or drop the class the curve naturally adjusts.
Grading on a curve is a practice used by teachers to determine student grades for assignments andor exams where grades are adjusted to reflect the professors desired distribution of scores also known as normal distribution. Most of the time grading on a curve boosts the students grades by moving their actual scores up a few notches perhaps increasing the letter grade. Grading on a curve can be done in a variety of ways though typically a teacher examines the raw grades that all his or her students.
Grading curves are often but definitely not always based on standard deviation - for example a score equal to the class average might be a B one standard deviation SD above might be an A one standard deviation below might be a C etc. If the highest score is a 95 that becomes perfect. While using curves is as simple as adding a point and bending your line up or down you can get quite precise and complex if you so desire.
