It's actually pretty common for JC/CC students to take 3+ years, and unlike 4 year college Athletics, you don't have to be a full time student. Many JC/CC students have jobs, family,and responsibilities beyond that many 4 year schools do. My dual college students are eligible for the CC teams as long as they take 6 credits a semester, and since most AS degrees are about 60 credits, 6 credits a semester would take 5 years to finish. Now, financial aid won't last that long, but as long as Navarro's cheer boosters can pay, and NCA rules allow it, they can stay enrolled. And as long as the Navarro cheerleaders are enrolled and in good standing, they probably can cheer. And if you are going for a professional program, you could get EMT I, then EMT2, then paramedic, and stretch those out to 5-6 years, especially if you don't go full time.
It also is common for community/junior colleges to have tutoring services available and a lot of support for all students, although having a dedicated tutor for cheer may be unique to Navarro. Their mission is to serve first gen college students and the kinds of stories La'Darius, Jerry, and Lexi had are not atypical.
I will admit, I'm trying to understand how anyone can handle college cheer AND Worlds level All Star. That's a lot of practice time, and Worlds teams usually travel quite a bit. I have no clue how Gabi could go to class at all if she was commuting between Top Gun and Navarro...not even counting her bikini shoots, modeling for Rebel, clinics, etc!
