【實用教育app】water quiz|最夯免費app-綠色工廠好玩App

Hi I'm Rohit a student from the Singapore American School and I created this quick quiz for you to test your knowledge with water and water related issues and learn something you never knew before, I'm am doing this for a water project at school and would really appreciate if you could donate to WFS or water for south sudan to help people in need of water. Thank you and I hope you enjoy my app.
