How to ask for a recomendation?

<p>I want to ask one of my coaches to write my 3rd recomendation, the one you get to pick. But, I don’t want them to think badly of me. I know they wouldn’t approve of boarding school. I feel like they would think i was using them just to get into this school because this year I increased the amount of hours I play at the facility. soo yeah. i dont know what to do.</p>
