BowB4Jeff,
NU plans to raise its percentage in a few ways (this is what John Lyons, the new pre-med advising director told me)...
1. Having a better advising system in place so that students know where to apply. This will lead to more kids being selective of where they apply and hopefully will result in better success for them. Until now, the pre-meds have been largely left to themselves to figure things out.
Better advising = higher acceptance rate.
2. New resources are being gathered with regard to data about where NU students with particular credentials end up. This will help students make better choices later on. Better resources = higher acceptance rate.
3. Lastly, more intense contacts are being built up with adcoms across the nation who are learning more about the intricacies/difficulties of NU's curriculum. If more people are better informed of what a particular GPA means out of NU, for example, then it might help out some students.
That's all I can think of for now.
Sandflea,
As for where I got the 55% rate from...Dean Weimar during a meeting early last school year. It was listed on the pre-med 'brochure' I received from him as that as well. Maybe, it was for first-time applicants only. John Lyons is really changing things, though, and it seems for the better in almost all respects. He really is much better organized and more helpful than Dean Weimar. Hope this all helps.
