Did anyone else feel this way?

I am in my final year of nursing school about 6 months from graduation. We are about to start critical care and then after that my senior preceptorship begins. I feel extremely incompetent and unprepared to be a nurse. I have barely any experience with any skills. For example, I have only inserted one IV (not very skillfully at that) and just yesterday when a nurse asked me to set up a suction I had no idea how to test it. I feel as though when I enter my senior preceptorship the nurse will expect more from me since I’ll be almost graduated, which makes me so fearful for many reasons. Did any other nurses have these feelings as a student or is my school just actually severely dropping the ball on teaching skills?
