Failed because of ATI

Had the final for LVN. Didn't get the score I needed to pass the class without all 5% of ATI. ATI remediation for a section was submitted "late" due to internet issues but was completed in time. School will not budge. Saying at their discretion to deny. My grades are really good considering my cognitive disabilities. I made the deans list multiple times. I am a non-traditional student. I had life outside of school. Family, work, my health etc. I can retake the course in the fall, but I really do not want to deal with the location I am currently at due to feeling the faculty are less than capable and the school/dean cares more about licensing pass rates over student success rates. 

I can appeal the decision through proper channels. All of my grades have been above passing by more than 5% in every term. Should I attempt to appeal, or should I suck it up and retake the course at the same location or try to find another location I can take it at?
