This App was created based on statistics and data. For university students, whether or not to get credits is a matter of great concern. Depending on the department and subject, students will often struggle because the weight of the evaluation of written tests, reports, practical tests, and attendance varies from subject to subject. University students are busy in many ways. "I'm so busy with my part-time job that I tend to miss a lot of classes." "I forgot to turn in a few assignments." "I partied a bit too much and now I'm struggling to keep up with my classes." "This class is a compulsory subject and must be taken for credit." This is the best solution for those who have such problems. If you know at an early stage whether you have a high or low probability of earning credits, you will be able to change how much effort you put into the class in the future. It will also give you a good opportunity to rethink the class as a whole, such as what you need to improve or what you need to focus on, if you think you may lose credits if you do not do so.
