I am currently applying to 21 schools, and I am just about finished with those secondaries. Because my stats were high and I feel like my other activities were decent, I applied to a lot of competitive programs. Now I am worried that I need to cast a wider net, and I am trying to gauge whether or not it is worth it to spend more money on my apps. If I send my primary application to more schools now, will my chances of getting an interview invite be significantly diminished?
