Initially, changes were made to the project structure. Participation and basic structure were added. Together with them, the project was reorganized and built on new features.
New features:

Firstly, I changed the folder structure. I designed base structure. The base structure include Android some support library so we can easily derive new classes and we can add new features.
Secondly, I used the base structure for Exams and Homeworks. I designed screens for easy use by users. I added components and I made the contents so users can add exams or homeworks and follow its.
To sum up, project structure changed so can easily add new features the app. Two new features added, its Exams and Homeworks.
