As for his visit to Tennessee, Jackson said he just had the urge to take a visit to Knoxville.
"For Tennessee, I don't even know why I want to go visit, honestly," Jackson said. "It's just something inside of me -- I just want to go visit their school."
Jackson moved to California two years ago, and he said his decision to move will help him with his college decision because distance is no longer a factor.
"It's just a great situation for me when I left Illinois, experiencing everything on my own -- being away from my family and friends basically," he said. "I came out to California and now I feel like I can go anywhere because I've already had those two years of being away from my family and friends."
Florida, FSU, Illinois, Notre Dame, Michigan, LSU, Tennessee, UCLA, USC and Oklahoma State are among Jackson's top 10 schools, but he has not planned any official visits.
