Introducing the credit system
Priority: Middle
After downloading the app, the user starts with 50 credits.
This credit score should be displayed throughout the screens at the same position.
Everytime the user answers a question correctly, the user gains 5 credits.
The user can then use these credits to play the random quiz (cost: 50 credits) to check her/his skill (Requirement: Random quiz needs to work)
Credits can also be used to allow an AI to generate questions for the user on a specific topic.
