This is the main menu for the "Teacher's Assistant" application. In fact it was millionth version🙈 But I did it after all. The main idea of ​​the application is to help teachers quickly grade students. So we needed picture of student, settings, calendar and classroom. Big problem was the last one. How do you imagine a classroom?? Finally it's a kind of door number. The project is complete, available on the Play Market.
