dissapointed

Hi my name is Denina and i am trying to get into the nursing program at the local community college. There is a 1 year waiting list but you have to pass a dosage calculations test. I took the test twice and I am ashamed to say I failed it both times. Now the reason that I failed is labeling. They won't let me review it and I honestly do not know what I did wrong. I have been a certified pharmacy technician for 5 years and I do those kind of problems every day at work. I don't know what I am doing wrong every time you do the test you have to do the practice test. I never ever missed a labeling question on the practice tests but when it comes to the test I don't know. And how am I supposed to know what I did wrong if I can't take a look at it. Can anybody think of something that could help me. I need to take the test( only three chances) again and I am so scared. I do not know anymore. I am not the kind of person the blames other people for my mistakes but I am beginning to think there is foul play involved as crazy as it sounds.
