Grades can be assigned as letters (generally A through F), as a range (for example 1 to 6), as a percentage of a total number of questions answered correctly, or as a number out of a possible total (for example out of 20 or 100). </P> <P> In some countries, all grades from all current classes are averaged to create a grade point average (GPA) for the marking period . The GPA is calculated by taking the number of grade points a student earned in a given period of time of middle school through high school . GPAs are also calculated for undergraduate and graduate students in most universities . The GPA can be used by potential employers or educational institutions to assess and compare applicants . A cumulative grade point average (CGPA) is a calculation of the average of all of a student's total earned points divided by the possible number of points . This grading system calculates for all of his or her complete education career . Grade point averages can be unweighted (where all classes with the same number of credits have equal influence on the GPA) or weighted (where some classes are given more influence than others). . </P>
