Homework Statement

Sorry if this is in the wrong place again... I have been asked to prepare a general overview of some aspects of quantum mechanics. This is extremely general, and it was intended we choose our own topics. Bearing in mind I'm 15 and self-tutoring, is this a reasonable attempt...?
I need to know if I'm missing any key vocab, or if I have not understood the topic correctly. I'm sorry it's quite long... Thanks for any help!
