Be neat, conservative, not overdressed. This means a jacket and tie for men and a dress or suit for women. During your interview be sure to ask some questions of your own. Don't be afraid to say that you don't know the answer to some questions, and don't try to bluff your way through something that you know nothing about. Ask for clarification if you are unsure about the question.
Most students receive some kind of financial aid to help defray the cost of their medical education.
Because of academic demands, most professional schools discourage employment of any kind, so you will probably be seeking some sort of aid. Administration of financial aid is usually done by the professional schools. On the day of your interview you will have a session with a financial aid officer who will discuss with you the grants, scholarships, and loans that are available to students attending their particular program. The manuals, Medical School Admission Requirements and Admissions Requirements of U.S. and Canadian Dental Schools also contain information on financial aid. This is an electronic resource manual for financial planning for premedical students, enrolled students and residents.
