Instructions for Mercer Calculators

Input Types:

Each calculator has an example to indicate whether a number or letter should be entered. When input is invalid, the results will be incorrect or will display "NaN" meaning numbers were not entered and are required.

Printing a Page:

The color scheme is orange and black. You may want to change your printer option to grayscale to prevent color printing.


GPA Calculator

The Course Name field does not affect the calculator, but it will help users keep track of which courses are represented on each line.

The Hours for Course field should contain the number of credit hours that each course is worth; most courses at Mercer count for three (3) credit hours. This field will accept fractions of hours.

The Grade in Course field should contain the letter grade estimated for the course. This field only accepts the grades of A, B+, B, C+, C, D, and F (either uppercase or lowercase input is valid). Remember to include all courses, even those that will earn F's, in the calculator. The following grades are not accepted in the GPA Calculator because they do not affect a semester GPA: W, S, U, IC, and IP. An error will occur if these letters are used.

If you are repeating a course this term, the grade you are estimating in the class will be calculated in your anticipated grade point average for the term. However, the calculator will not take into account any repeated course(s) you may have this term when determining your new (overall) cumulative grade point average.

The Semester GPA and Overall GPA fields are truncated to three decimal places.


Weighted Average Calculator

The Assignment Name field does not affect the calculator, but it will help users keep track of which assignments are represented on each line.

The Assignment Grade is the number of points awarded for each assignment out of 100 points. Fractions of points are acceptable input.

The Percent of Course Grade field is how much the assignment counts toward the final grade. When all assignments are listed, the Total Percent Listed, which is calculated automatically, should display 100. If this is not the case, then the input may contain a typo.

The Course Average field is truncated to two decimal places for easier reading.


Points-Based Calculator

The Assignment Name field does not affect the calculator, but it will help users keep track of which assignments are represented on each line.

The Points Earned field contains the number of points awarded for the assignment, which is usually less than or equal to the Points Possible. The calculator will accept a higher value for Points Earned than Points Possible, since extra credit could be awarded.

The Points Possible field should contain the total number of points that each assignment is worth. When all assignments are listed, check the Total Points Possible field to see if your input contains any typos.

The Course Average field is truncated to two decimal places for easier reading.
