Average & Passing Grade funktioniert nicht

Because we all had that one teacher who gave us a grade over 42, "Average & Passing Grade" lets you enter your grades in the base of your choice, individually for each examination, for more personalization.  Very simple app that computes your averages, in addition to your overall average and the minimal grade needed on a final exam to reach the final average you want in a course.  Just enter your desired average and all the grades you already have, along with their corresponding coefficients, and the app computes your average in each course, your overall average for the semester and the passing grades!  Simulate the grades you have not received yet to predict your passing grade, your average in a course and your overall average!  Depending on your needs, you can also choose your own base for displaying your current average or your final grade to achieve.  Easily modify a grade in an examination to see the consequences for your average or your final grade to achieve.  To better compute your average, you can enter different coefficients for each examination.  To better compute your overall average, you can enter different coefficients for each course.  Useful if you want to know your passing grade in an examination!  You can add multiple semesters to see your annual average and to see your overall progression.  You can enter several courses in the application, your data is automatically saved on your device!
