How important is it to visit each college and network with the admissions reps?
Speaking as a former admissions officer, this is actually a very important thing for students to do. Be sure that your particular admissions officer knows who you are! Also make sure that you make a good impression, use proper etiquette and manners, project yourself as an independent and responsible young adult, and express your enthusiasm for the school. Admissions officers meet many people, but remember the students who are either well prepared or completely underprepared. Keep in mind that the person you see at the college fair or speak to on campus, will often times be the same person who is reading your application. Any time you have the opportunity to get in touch with these people make a good impression, as it can be the difference maker when the admissions officer is reading your application.
