On average, Ivy-caliber kids are smarter, come from better schools, and have brighter, better-connected parents. You probably could lock Ivy-caliber high school in a closet for the four years of college and, on average, they'd end up with much better careers than other students.
Cover Letter vs Letter of Interest. A cover letter is a formal letter that is sent together with documents such as resumes and other items when an individual is applying for a specific job. letter of interest, on the other hand, is a formal letter which is sent together with the resume to inquire about a job opening in a company without any job specified. It is meant to inquire about employment possibilities in the company with no specific job in mind.
Your cover letter should include an expression of your interest in knowing more about the job. At this stage in the process, you want an interview. Your cover letter shouldn't state that you want the job, because in many cases, that's premature and gives your cover letter a tone of desperation, which is counterproductive. You won't know whether you want the job until you have an interview.
