If you're a regular reader of my Admit This! blog, you may have noticed that I put a lot of emphasis on what I call "student profile marketing." That phrase refers to how you, as an applicant, can create through your application the optimum presentation of who you are and how you think.
A big part of "who you are" comes from telling the admissions committees what you do in addition to your academic work. These pursuits are known as "ECs," or extracurricular activities.
