Waitlisted Help

Hello all, just heard back from my #1 school, Quinnipiac University. I have been waitlisted. It says last year they accepted 25% of students off of the wait list. Im wondering if I should write and essay to admissions expressing my high interest in this school. I applied for psych and also didn’t get a recommendation from my psychology teacher. Maybe getting her to write me a recommendation along with a short essay to admissions would strengthen my chance? what do you guys think?

Can’t hurt, and whatever you do, definitely express continued interest.
