I'm still with the whole "your teacher is terrible and if you got a 100% on that test then there's something wrong with it" hypothesis. You thought "boku" was formal and you're writing isn't only verbose and legalistic, it sounds handicapped, completely lacks the basic kanji components, and even uses the wrong particle for "wa". And rather than admitting you're wrong, you try to make up excuses for your mistakes that make you even more wrong and handicapped.
