1. format is like a narrative. The critical letter is written in the middle. Text starts on a new line with two spaces. The first paragraph: write directly what you want to review in a straightforward way. In other words, write that you violated discipline or rules. The second paragraph: write out how to correct it in the future and not violate it again. The third paragraph: ensure that you play an exemplary role. Finally, sign your name and write down the time.
