Middlebury Summer Language School Acceptance Rate

My question is aptly suggested by the title - does anybody happen to know what the acceptance rate of Middlebury’s summer language schools are?

In particular: I graduated from my undergrad a couple of years ago with a high GPA (3.9+) in a humanities field and would like to take a class in a language that I never studied before in university. I’ve studied that language informally in the years since I’ve graduated, through the help of a private tutor (whom I’ll be using as my recommender), as I was living in a country where the target language is spoken.

That having been said, I’ve decided that it would be good to get some formal training in the language as well, which is why I’m looking at the Middlebury program. I’m just wondering if anybody can speak to any pitfalls in this application that I ought to be aware of, or if anybody has any general advice about the application process.
