I'm in 3rd semester of AD nursing. I just took my second test this semester. While I was reading the questions I was thinking "OK, maybe I'm not able to do this!!!!" I felt a little better when there were other "smart" students that was saying the same thing. I went to clinicals yesturday and I got my confidence back, AGAIN... It won't be the last time I feel that way I'm sure. If you feel this is what you are supposed to be doing then just keep going.
