This application is for students who don't want to waste their time calculating grade or average of their courses. The most important difference between similar apps is that it is possible to add or remove courses or marks thanks to 'Add' and 'Remove' buttons. So that it can be used by both high school and university students.
This app has 3 parts :
Grade Calculation In this part you enter your final and midterm marks with their percentage so this app gives you your course grade out of 100.
Average Calculation: When you enter your courses' grades with course credit, you can learn what your average mark (GPA) is.
How much required to pass? When you think that 'How much I take, I will pass this course?', this app helps you to calculate it easily.
