well its hard to say since not everyone on here posts. but it think people on SDN does have the upperhand in getting into dental school than people that don't visit this site. this site link us to people from all over and i don't think there is a question that goes unanswered, versus people who don't visit here, they get their predental questions answered from people they know in their area or by contacting schools. i also think that this forum is a big advantage for the DAT. the study tips that each people post on the DAT is very helpful, i guess this is why SDN DAT averages is higher than the norm.
