Well, this is an Honors College after all. Here are three calculators that will enable you to answer a number of questions—if you really want to know the answers...
Semester and Cumulative GPA Calculator
This calculator will compute your GPA for a single semester or, if you know your current GPA and total number of credits, it will compute your cumulative GPA including these current grades. It should be self-explanatory and you can use either upper- or lower-case letters for the grades. It will also compute your new GPA after a semester's grades, providing you know your current GPA and the number of credits you've taken.
Target GPA Calculator
This calculator will tell you what GPA you will need for your next semester, year, etc. to reach a GPA goal. You just need to know your current GPA and the number of credits you've already completed. Then choose a target GPA and a number of credits in which to attain that target!
Course-Repeat GPA Calculator
This calculator will allow you to compute the effect of retaking a course with the new grade replacing the original one. Note: If you retake a course, do not list that course in the Cumulative GPA Calculator — that calculator will just add it as if it is a new course. To find you actual new GPA, use the Cumulative GPA Calculator inputting the non-repeated courses and then use this one to see the effect of the repeated course. Here you need to know your current GPA and the number of credits you've completed, and, of course, the number of credits and the two grades (as always, you can input either upper- or lower-case grades) for the course in question. Before deciding to re-take a course, please review the University's course repeat policy which is reprinted below the calculator.
Right now, you can only replace one course at a time, though of course, by using the calculator sequentially, you can see the effect of repeating several courses. However, if there is demand, I might be able to rewrite the calculator to take several courses at a time. If you are interested, let me know.
University of Maine Course Repeat Policy: A student may repeat a course regardless of the grade or grades previously earned in that course. Full tuition is charged each time a course is repeated, but credit for a given course may be earned only once, even if the course is passed more than once. When a repeated course is failed, any previously earned credit for that course is lost. Only the most recent grade earned in a repeated course counts towards the accumulative grade-point average, even if the most recent grade is lower than one previously received for that course. The grades for all attempts of a course taken for credit appear on the student's transcript.
