"There was no need for me to stay in 2013 because all of my classes would be finished for next year," Purvis told Scout.com.
"I had all my credits in order to qualify," he added. "I'm working on my SAT stuff now. There wasn't a need for me to stay around high school and waste time."
Purvis, a standout at Raleigh (N.C.) Upper Room Christian, said he ran the decision by the college programs recruiting him. According to Purvis, his reclassification won't affect his recruitment.
"It doesn't at all," he said. "I have to admit, I confirmed it with [the schools] before I did it. That was another important factor in my decision."
As far as the recruiting process goes, Purvis said he's just taking it all in right now. His list consists of Duke, Memphis, North Carolina, Louisville, Kentucky, Texas, Xavier, Wake Forest and Virginia Tech.
‘It's going really good," he said of the process. "I'm just enjoying it. It's fun."
Last weekend he took an unofficial visit to Xavier, where his AAU teammate Dezmine Wells will attend.
"It was really fun," Purvis said. "A player from my team goes there so I felt comfortable and it was fun."
Tonight Purvis will head to Durham (N.C.) for Duke's midnight madness festivities.
"I like them because they are close to home and they have a great coach and they have a great tradition with guards," he said of the Blue Devils. "Duke is just a special place."
Following the Duke visit the only other trip Purvis has set up is to go to Louisville next weekend.
"I have a good relationship with Tim Fuller because he used to do the Nike stuff," Purvis said. "I give him a call two times a week and we chat it up a little bit."
"We have a good relationship, but it doesn't help with the decision," he added. "He's not even trying to lure me or anything like that, it's just a good relationship that we have."
Purvis said he's not worried about making his college decision anytime soon. In fact, he's more worried about getting better on the court.
"Actually I'm just working harder," Purvis said. "I'm just working harder. I want to be one of the best in 2012."
