i am an incoming nursing freshman. i wanted to make nursing as my premed course. however when i visited the websites of medical schools, i've seen that they have specific requirements like biology w/ lab, inorganic and organic chemistry w/ lab, physics w/ lab, biochemistry, etc. i reviewed my degree plan and all i is a biology w/ lab class and introduction to chemistry. almost all of the majors that will be included in my 4 year BSN are nursing courses like health promotion and education, nursing concepts and processes, etc. I am worried that my BSN program will be insufficient to provide me the requirements i need to get into a med school. does that mean after i graduate my BSN and take my licensure exams, i need to take additional subjects in order to obtain the requirements needed for med school? is it possible that i study while i work as a nurse? my academic adviser is also suggesting that i consider Nurse Anesthesia. If ever i pursued nurse anesthesia, can i still go into a medical school after? i know it will take me a lot of time in school, but it's ok with me because i have passion for learning and i will do everything just to achieve my dreams. i really want to be a doctor but i dont think i can pay for the medical school expenses that's why i wanted to work as nurse first and save up for my medical school. please help me, im really confused right now.
