Yeah.. ummm if this is true... I'm sorry to say but you need to give up on nursing and save your money and the lives of your potential patients. I dont even think any respectable hospital would or should hire you. I totally understand failing 1, 2, 3 Even 4x but 21 means you simply can grasp content and retain information. No hard feelings but nursing is not for everyone. I know engineers that couldn't grasp the concepts of health sciences.
