Do I have to get all points from the point system for ADN

What points? Are you asking about a specific school's point system?

Based on the other threads you've started today you seem very focused on the point system employed by some community colleges. You do NOT need to get ALL the points in order to be accepted. It would be near impossible for someone to meet every single category for which extra points may be awarded.

Typically what is needed is a MINIMUM number of points in order to be considered for admission (e.g. perhaps a college requires all applicants to have at least 70 points out of a 100 in order to apply and be considered for admission) This is simply a method for schools to weed out some applications and prevent admissions officials from being completely overwhelmed in reviewing applications. Other schools may do this by having a minimum number of pre-reqs completed at time of admission, or minimum GPA or test scores.

Military service, health care experience, prior degrees etc may all add a few extra points here and may be a way to acknowledge students who have valuable life experience, however the bulk of points in every point based system I have seen focused on grades, and one can meet the minimum required points through grades alone if getting good scores in course work.
