At my school we don't go thru interviews- admission is done by preference points. They line up all the points and take the top 55 people. There are no wait lists, you must apply each semester. The points are awarding for gpa, courses, net scores, compass scores and previous degrees and certifications like cna, cma, etc. AND-if a person has the minimum gpa but high points- they get in over another applicant who has high gpa but less points. Ya it's kinda weird! BUT less subjective than a director getting a "feeling"

They accept around 20%. 50% would be great!
Pretty much now everyone has to have all pre-reqs finished and support courses as well (these used to be done within the program) BUT it's so competitive that it takes a while just to prepare for application.
When I apply in March I will have 22 out of 24 points (lowest accepted last semester was 18) I will have taken the following:
AP I & II, Clinical Calc, Med Terminology, Micro of Infectious Disease, Pharmacology, Nutrition, & Dev. Psych. BTW I have a previous degree in a science so I haven't had to take any general ed classes like english comp, algebra, etc. A grand total of 27 hours BEFORE entering the Associates Program. Because of the point system, it just can't be done any other way. AND all the schools use a similar system, even the major university NS.
I guess I would say do what ever it takes-take all the classes, make as many As as possible, volunteer or work in health care, and practice interviewing.
Good Luck!
