Congratulations !! Hopefully you will continue on this path, no matter what. As Cali wrote, is not easy; it is hard, it is time consuming, and it is difficult to get into a nursing program. However, if you persist, one day you will receive your acceptance letter in the mail, yey!!!!!!
I would say that it would be cheaper for you to enroll in a community college to take the pre-requisits for most nursing programs (anatomy, physiology, statistics, microbiology, etc), and make sure (asking counselors), what classes do you need to take before. I had some friends who took wrong classes and had to wait another semester to be able to finish pre-requisits. Get information from those possible colleges you would like to attend, though most colleges ask for same requirements, it could be some little difference between classes.
Some colleges also require volunteering time in hospitals, so ask around, and do not be shy, whenever you see a nursing student, ask them because sometimes they would give you great tips.............
Hope to see you here often!
(This is my first semester in the nursing program and I am just loving every minute!!)
