I've had two med students recently tell me that they felt intimidated after reading postings from other applicants on the student doctor sites. In general these web sites can be very helpful; but please don't take other people's braggadocio to heart. If you think the comments are affecting your confidence take a break from reading them. You want to approach your interviews with self-assurance.
