Minha Nota play online

Minha Nota is an application that aims to help university students calculate the grades needed to pass a given subject.
The user informs his grades of the first 2 evaluations and AV3 and/or AV4. Based on this data, the application calculates the required grade in the 3rd or 4th assessment and in the final assessment for the student to pass the subject. While the calculation is being done, an animation is shown on the screen, with positive, negative or neutral feedback.
