"You needed to basically get to a five, so he's been working for the past two years with Peter Cassidy.
"He's got him down to a four. Normally it's a 10-year programme to get that low."
Bradley Wallis said Cassidy, who had played in the United States and knew what it took to do well, spent the first month working on his swing, then helping him with the finer points of playing through the course.
"It was more learning what to do when you get in trouble " course management."
Wallis will start a four-year accounting degree at Patrick Henry Community College, who have a relatively new golf team competing in Division III of the National Collegiate Athletic Association (NCAA). His scholarship covers some of his tuition and all of his golfing expenses " as he will study in the mornings and practice in the afternoons, while playing games on the weekends.
A highlight will be the prospect of teeing off at the nearby Sedgefield Country Club in Greensboro, North Carolina " which is home to the $US5.4 million Wyndham Championship.
"I'm really looking forward to playing on that one and hopefully watching the PGA event," Wallis said.
The Patrick Henry golf team came 12th in the NCAA Division III national championships last season, and under the agreement, it is possible for Wallis to transfer to a school who plays Division I after two years.
"The goal is to turn pro after I come back," he said.
Based in Purcellville, Virginia, Patrick Henry is a private, independent college with an Evangelical Christian basis which focuses on teaching classical liberal arts and government.
Established in 2000, it has a roll of around 350 students, with the major sports being basketball and soccer.
Wallis will head over with his parents for the start of school on August 18.
Other teenagers to have taken up sports scholarships to American universities in the past few years include Shaan Stuart (soccer), Paige Hourigan (tennis), Kyle Butters (tennis) and Thompson-Newth (golf).
