Letters of recommendation carry varying weight, depending on the perspective of the college or university and who writes them. The more selective colleges may ask for two or three recommendation letters.
Questions abound: Whom should you ask? What are they used for? Where do they go? When should you ask? Why are they important? And how do you prepare them to write the best letter possible?
Colleges prefer letters from junior-year teachers because they are the most familiar with your most recent work. Read instructions carefully, since some colleges may specifically request a science or math teacher, especially if you’re applying to an engineering program.
