my QUIRK

My biggest quirk is to colour in the title of the History exams with Barça colours, I have been doing this since I was in 3rd of ESO, when Nil and I painted the title and we got a 10 in the exam, during the time that I have been doing this, i've always passed the exams with a good mark.
It's possible that my marks aren't for this reason, but I like to do it because it gives me confidence in the exam and during the exam I entertain myself. Before the last History exam I explained my classmates what I do, and they all said that they will do it, but it's my quirk and I like it and I hope that the teacher also likes it.
