<p>Having connections. Other than that it is a toss up. However, do not be so desparate if you do not get into PPSP. D. was rejected pre-interview 4 years ago. Went to another bs/md at state school. Applied out to several Med. Schools outside of her combined program. Got into Case (that first magical night of Oct. 16 when Med. Schools are allowed to call their first acceptances, which indicated that Case really wanted her) and few other Med. Schools. Choose to go to Case, turned down Northwestern Med. School for Case, felt that Case is a better fit for her.
So, do not be too upset if you get rejected. You will have chances later.<br>
BTW, there is no guarantee for any bs/md, all of them are extremely selective. However, if you apply widely and not only to most popular ones, you will have a better chance. D. was accepted to 3, all at IS state schools four years ago.</p>
