To have been mostly given the option of withdrawal seems to me that something occured during your pediatric clinical rotation. Perhaps you should identify how this should be corrected in the future. I think for any institution American and Caribbean alike it is going to be difficult to allow you to start over especially after having been through some of your clinical rotations which signifies that some adverse event occured with a patient that led the school to give you no other option. Good luck in your future endeavors.
