"It's the same schools, but its still picking up," Booker told Scout.com. "I think they feel like it's coming to an end, even though I don't have an end in sight. It's picking up."
Booker, a 6-foot-4 guard, said Kentucky has increased their interest as of late.
"It's picking up," Booker said. "[John] Calipari is developing a relationship with me. We talk everyday. Me and a few other players like me and Stan [Johnson] talk about it sometimes. I just want to visit the school and go from there."
While home visiting his mother in Michigan, Booker stopped by Michigan and Michigan State. He's been to each of there campuses multiple times, but had an opportunity to talk to the coaches and walk around campus again.
"It was real good," he said of Michigan. "I've been there seven times. I went to their team camp thing. Me and my friends went down there and went around the campus. I've been down there so many times, it was just to talk to them really."
"State, that was like my fifth time going there," Booker said. "[Tom] Izzo is a real cool guy. We've developed a relationship over time. They came in a little late, but the relationship is great. It's a close school to my mom. They are 35 minutes away. She wants me to stay close to home."
According to Booker, Missouri and Florida are both heavily involved with his recruitment as well. North Carolina and Duke were recruiting him but he said their interest "slowed down once their commitments came."
Missouri has been recruiting Booker the longest and he has strong ties to the program because his father played there.
"That's my dad's alma mater," he said. "They've been recruiting me since the 8th grade. Their fans show me so much love every time I go. I just developed a good relationship with Tim Fuller and Frank Haith over that time too."
With Florida, Booker said the draw is their offense. He likes how Billy Donovan uses his guards and the style the play.
"Just Billy D's system," he said when asked why he liked Florida. "He runs a NBA offense and pick and roll with the wings, which is the NBA today. I felt comfortable down there. I visited and there are a bunch of good dudes down there."
Despite having visited four of the five schools involved, Booker is planning to take some official visits.
"I think after the summer I'll officially cut it down and then I'm going to go from there," Booker said. "I don't know how many officials I'm going to take. When I feel a place is the right place that's when I'll decide."
Booker, a four-star recruit, is currently ranked No. 31 overall in the 2014 recruiting class.
