The story behind Central High is fascinating.
Here’s an excellent article in the Atlantic, on schools in Tuscaloosa (including Central High) and the changes that have happen over the years.

Top students (the limited number that they do have) at Central HS have options other than UA. For example, last year at FAMU, a 3.5 GPA and 29 ACT would have qualify an OOS student for a full 4 year scholarship that pays tuition, fees, room and board. Plus STEM majors got laptops. At UA, an in-state student with a 29 ACT score would have received 1/2 tuition scholarship.
