OU SON packet

Hi all! I just recieved my OU info pack today. It is not clear on how they accept students. Does anyone know how many students apply? I know they accept 75 twice a year, but how many students are applying and are they making acceptance decisions based on GPA alone? Or are you guaranteed to be accepted with the credentials listed (2.0, pre rqs, etc.) I am so so so stressed out about getting into to a school. Currently I am at oakland community and this fall will be my last semester before applying to their ADN program, but WHAT IF I DONT GET IN?!?! Then what? I am trying to devise a "plan B" and am not sure what to do. HELP! Is anyone else in the same situation? or am I alone?
