Have the computers made a mistake? You have been attending Northeastern State College (which follows a percentage grading system) for two years. You have received good grades, but after four semesters you have not made the dean's list, which requires an overall average of 90% for all accumulated credits or 90% for any given semester. Your grade reports are shown in Table 7-22.

To find the grade point average for a semester, multiply each grade by the credit hours. Add the products and then divide by the total number of credit hours for the semester. To calculate the overall grade point average, proceed similarly, but divide the sum of the products for all semesters by the total accumulated credit hours. Find the grade point average for each semester and the overall grade point average.
