Nearly three months later, he left his hometown, Washington, D.C. , and enrolled at Oak Hill Academy – known for its basketball pedigree – in southern Virginia.
"I've just been working out and getting ready," Britt said of his final days at home. "I'm trying to spend some time with family also before I go, I'll go visit some of my aunts soon. But mostly, I've been working out, doing a lot of shooting, doing some pool stuff, lifting some weights and a little bit of everything so I'm prepared for what's coming."
Britt, like roommates and fellow UNC signees Kennedy Meeks and Isaiah Hicks, received a workout routine to follow from Carolina's strength and conditioning coach Jonas Sahratian. Britt called the regimen "different."
"It wasn't too difficult," the 6-foot-2 point guard said. "The workout is based on body weight. I've done most of the stuff they have sent, but there was still a little bit of an adjustment."
Despite a meniscus injury that cost him several weeks in the middle of this past season, Britt is pleased with his on and off the court growth during his senior year at Oak Hill.
The injury took Britt a while to recover from both mentally and physically. In fact, he said he didn't feel 100 percent comfortable until Oak Hill's final tournament of the season in April.
"It was a very good experience for me to get away from home and mature off the court," he said. "I had to manage my time on my own and get everything done by myself. On the court, playing with high-major division I players is pretty similar to how it would be at UNC. Me being a true point guard, it just helped me out a whole lot."
Communication between Britt and the UNC staff has been pretty consistent. Britt talks with assistant coach C.B. McGrath the most. Their discussions range from Britt's work in the classroom, to his family, to his role at UNC during the 2013-14 season.
"I think they see me being able to contribute when I come in," explained Britt. "They've told me, especially coach (Roy) Williams, that they can better evaluate me when we start doing workouts and things like that in the summer. He feels like he can tell me what I need to work on and where I'll be once that starts."
Britt committed early in his junior year, so the anticipation to get to Chapel Hill has been growing for more than 20 months.
"I'm super excited, I can't wait to step on campus and finally be a part of the team," he said. "After I committed I was very excited and throughout the rest of high school it died down a little bit. Now that I know I'll be on campus so soon, I just can't wait to start and be around the guys."
Britt will wear No. 0 next season, the number currently worn by rising sophomore center Joel James. According to Britt, James will switch jersey numbers next season.
"I started wearing it in high school when I first was at Gonzaga (high school)", he said. "I had always worn No. 4 or No. 5 before that. I wanted No. 0 because most people didn't think I'd be as good as I was. Wearing the number reminds me of what people expected of me."
