False, many healthcare degree programs have this requirement. University of Washington pharmacy program, University of North Carolina school of medicine, Duke physical therapy program. Also, Evergreen college masters of environmental studies. This requirement is not unique to nursing, it is found in many healthcare degree programs.
You are thinking of nursing like any other field of study, but it isnt. If I want to to obtain a degree in art history or ecology I could do so without ever doing more than signing up for the required classes. That is not how nursing programs operate, you have to apply to be accepted into a program. Because their is no national standard for nursing program entrance requirements each school is able to set their own requirements, which can and do include the time period in which you need to have taken certain prerequisite courses. The difference in this time frame from school to school comes down to individual institution autonomy.
You have zero grounds to seek legal action, you have sustained no damages, you have even stated that there are schools which do not have this "money hungry" requirement.
There is nothing stopping you from applying to a school that doesn't have this requirement, many students move cities or even states to attend nursing school.
You can be angry, entitled, and stomp your feet all day, but in the end you know what will be required of you to gain admission to a nursing program, these are the hoops you are required to jump through. No frivolous lawsuit or demanding evidence from strangers on the internet will change that. I understand that it can feel frustrating having to retake classes, money and time don't grow on trees. But litigation is not the answer, if this is a career you are truly passionate about you should put your head down, jump through the hoops and do what you need to do. It will be very worth it in the end.
