Tweet Colleges want to know the real you. But getting to know you as a person, your personality, what drives you, what moves you, and what you are passionate about, is difficult for colleges. They can’t figure that out from your grades and admission test scores. (As they say, you’re not your grades and test scores.) So colleges rely on other, more human sources. And one very significant way they gain insight into the real you are through college recommendation letters from your teachers. In fact, as admission test scores have become less of a factor in deciding who is admitted, teacher recommendations and application essays have become more important.
