Very interesting. I wonder how he got admitted to college when he had not yet completed his high school work?
Our school district here in McKinney, TX has coordinated program with some local colleges to allow “co-enrollment” for advanced students. I think some of the college classes can also be counted as HS credits.
It’s called dual credit. My kid did it. You can take college courses that count as high school courses too. Mine hadn’t racked up enough credits to graduate with a BA by the end of HS (in our area they limit you to 15 per term for 3 years...so technically you could), nor did he do the extra curricula stuff this kid did. But he did finish 12th grade with his HS diploma and an AA (78 transferable hours) so he was able to graduate college with a BA at 19. This kid’s feat was phenomenal in that he did both plus extra curricula. My kid opted out of the HS part and you’ll find plenty of kids doing the same these days. I think I know at least a dozen kids who graduated this year with their HS diploma and an AA. And to answer your question, you get your HS diploma and then they award you the BA or AA right after that. You get into college by testing in, you usually have to score a certain level on the college level placement test (in our area, you have to be able to test into College Alg, and Comp I.)
