The 2nd type is what they refer to as "The Medical School Experience". Here is how this works-for those applicants who have a sufficiently high gpa and MCAT score, the decision is made to forego the standard interview process, and these applicants are invited to attend this special prorgram which essentially serves to "sell" the school to this subset of "high-stats" applicants. There is no interview for these applicants, and if you are invited to attend, the decision has essentially already been made to accept you. Nova recognizes that these applicants, due to their high stats, likely will have many choices regarding what school to attend, and a great number of these applicants are hoping to attend an MD school, but have applied to Nova and other DO schools as a "safety" in the event they are not accepted to an MD program. Nova uses this "Medical School Experience" day to attempt to draw in some of these applicants and convince them that Nova may be the better fit for them.
