I was thinking if having a powerpoint would be necessary to present
He just posted a memo about it today, but basically it's a 2-3 minute presentation about design principles and teamwork, then a 10ish minute demo of your app and its main features, then 5 more minutes for questions from the other students.
I think in the slide we mainly show design pattern, design principle and UML of our app.
i just added the UML diagrams of the project in the presentation
