  • Application
    Does the project have any feasible application in real life? Does it seem like something that someone could use or would actually have a benefit in the real world?
  • Functionality/Quality
    Is the project free of major bugs? Does it look appealing? The UI/UX doesn’t have to be absolutely perfect, but if we're having a hard time understanding the project by looking at it, there may be a problem.
  • Creativity
    Is this project unique and innovative? Is it a solution to a problem we have never seen before? A better way of doing something?
  • Technical Complexity
    The team should display a good level of knowledge in terms of the technology they’ve used in implementing their project.
