Good afternoon.

If you are required to submit these letters the teachers are the ones that are to write them for you, about you. Letters of recommendation are kind of these individuals' "word" or "honor" that you are suitable for the university and/or the course of study. Your instructors should be familiar with these letters and should have no problems writing them for you.
