The summer wouldn't be too hot and the winter wouldn't get too cold. The seasons would come and go at a normal pace. In my world there wouldn't be classes that would be boring. There would be classes that would educational at the same time be interesting. Teachers in the schools would get paid a lot of money so they would have somthing extra to teach for.
Teacher have to put with kids almost all day, everyday.
In the school there would teleporter machines that would zap students and teachers to their classes. These teleporters would make it easier and faster for people to get from one end of the school to the other. But there would still be stairs for people to walk on. Pollution would really exist but it would be changed to help the environment. In my world most disease would have a cure or would have been cured.
