Copyright notice and disclaimer

Hello. Recently I just finished a personal project, which is an inventory system plugin. I gave it an MIT license, but still have some questions about copyright stuff.

  1. Is this an okay copyright notice?

  1. Do I need a copyright disclaimer from my school? The project is not related to school. But I started it when I was in school, and completed it after I graduated.

Bump to this question, since it’s the first search result for unreal engine copyright notice disclaimer.

Would this be fine in such case?
