Some people like to send more resumes, but I personally don't think it is necessary because my prize &; Achievement (certificate/major, etc.). It has been mentioned in the extracurricular and essays of the common App. I don't think it is necessary to get another resume, because there is no new information to add.
The teacher of the Admissions Office of a famous school also said: "The resume is ok, but the most important thing is to write the column of additional activities well. Many students sent a lot of good additional materials, but they didn't fill out our form, which is wrong. "
In short (as the teacher of the Admissions Office said, it is also my personal suggestion), that is, first complete the basic requirements, write the commonly used app additional activities correctly, and add your resume if there is value-added.
