I am in my last semester in nursing, I am mid thirties and my work history is terrible, I do not want to list any of my past jobs. The last jobs were a few months ago: first one was at a hospital last a month due to poor grades, second at a nursing home hours were awful and grades dropped fast lasted 2 months. Before these jobs the last time I worked was in 07.. I applied to a hospital electronically to a well known hospital that I REALLY want to work at but no response and it's been two months. Should I send a cover letter and If so how do I explain my situation?
