See if the nursing lessons you are going to take will be taught by certified instructors and what type of experience ort credentials that they have. Make sure that the instructors are able to work with you and try to help you succeed, not someone who is out to just make everyone fail.
Try to determine how long you will be in the nursing lessons before you actually go out and take them. In many cases it is a two year program, but that may be contingent on you being able to meet their scheduling needs not their ability to work around your needs.
