Consider GLMA. Average age of student is 27. When I graduated, the class size was around 50. We had two guys in their 50’s, two guys in their 40’s, and a handful of guys in their 30’s. To be a 22 year old graduate there is a bit of a rarity.
In addition, you take all your Gen Ed classes st the local community college. It seemed to me that they really cared and had many resources for math/English challenged individuals. There was a math lab that always had a tutor available, as well as an English tutor who would read any paper and offer guidance. To be honest, the only people the failed the Gen Ed’s were usually people who stopped caring.
