So, it either took him 9 years to earn his undergraduate degree which would be unusual for someone getting into medical school, OR, he earned his degree in four years and did something else for 5 years.
The time from age 18 until completing UVA at age 27 need to be accounted for.
I didn’t start college until I was 25...sometimes, people do other things, or nothing at all for years between. It would be interesting to see how he spent his years...
