Not familiar but it sounds similar to other scholarship weekends or days - maybe not as in depth. But based on the performance, you may get named to an endowed scholarship or university one. They list them here.
It’s similar to the College of Charleston Fellows (another to look at) and the W&L Johnson - maybe not as in depth as it’s a one day thing but….at some, they may see how you interact with others, as an example.
There are others too. Mercer U as an example.
I’d imagine it’s well worth attending - especially for a student with your stats - who should apply to more schools with these type programs.
