Why the wait lists?????

So as I finally get to the excited point of my college career where I see the light at the end of the tunnel. I get smacked in the face with the last thing I wanted to hear. With only one semester left (Winter 2014) I decided to go meet with a guidance councilor to make sure I was in all the right courses and that I can validate for clinicals, He says "yes mam you sure can"! I was filled with excitement! I was so close I could taste it! But then he says well we take 18 students every fall for the radiology department and currently we have 64 validated. WOW so my dreams seemed to be crushed in an instant. So today I decided to look around at other colleges well non in the area have radiology. So my next plan will be to go to school for my minor which is going to be phlebotomy to get me into a hospital so I can be ready to transfer when I get my major I will have already have my foot in the door! Most places hire within first so that's my goal for now. I guess you should always have a back up plan!
