Hi Delta2017. Great idea to attend information sessions and any other admissions-related events at the schools you're considering. The more contact you have with each school, the more you get to know the school and you'll be able to detect the nuances between different programs. In terms of making an impact, it's hard for applicants to stand out or be noticed and to be honest, Admissions will be more focused more on presenting program information and answering questions, not on evaluating candidates.

However, you want to make sure you do NOT make a negative impression, as this is more likely to stand out and get you noticed. When I led information sessions and mingled with attendees at these events, sometimes there were applicants who would dominate our time (by trying to ask way too many questions even while other attendees were standing next to them waiting to ask a question) or who interrupted or who made derogatory comments. The advice I have is to be courteous and receptive to learning as much as you can. It's always a good idea to come prepared with a few questions (not questions with answers that can easily be found on the website, though) and hopefully you'll gain some new insights into the program. If there's a current MBA student or alum at the event that's a great opportunity to learn about their experiences as well. I'd suggest you take some notes from the session as these might be useful when it comes time to writing your essays or for your interview. Hope your info sessions turn out to be productive!
Thanks,
Dina
