The admissions committee has carefully reviewed your application. After much consideration, it is with great regret that we must inform you we are unable to offer you a spot in the beta course.
The course was extremely popular and there was a large number of strong applicants; in light of this, we were unable to offer a spot to every worthy applicant.
