No it is not a novel. An autobiography is a form of biography written by the person that the biography is about. A novel is a fictional piece of work that has characters(dynamic, static, etc.), plot, rising action, falling action, a climax.
I guess another answer is mentioning that there is something called autobiographical novel.
Well the introduction paragraph introduces what you're talking about and the conclusion paragraph is used to draw the final point, or get whoever is reading your text to agree with your opinion or what you were writing about
