Importance of ranks

People can change really quickly i just don't know what to say and it appears that he is on a class higher than me I'm quite disappointed I didn't even remember doing bad things when I was on middle school. The bell rang and a teacher of magic academy assemble the students we are all gather in one spot then she used a magic that can used as microphone. " All the students of magical academy this is the start of your lives on being a magic knights". all the students entered the school I can see some familiar faces form middle school, the school is like a mansion the rooms are really fancy I looked around and I don't see my class, other students are entering their classes then a teacher approach me and said where is my class I said it's class seven she apparently change her attitude towards me and she turn on some what kind of delinquent but thankfully she lead me the way to my class. Ranking is important here i can change that maybe there is some kind of mistake that I am on class seven. We walked and the structure of the mansion is different now form fancy to kind of scary room it's getting darker and darker I don't know if it's the magic academy anymore.
