The previous record-holder was Jon Diebler, who scored 3,208 points from 2003-07 before playing at Ohio State.
He came into the season 981 points away from passing Diebler. On his way to the top of the record book this season he passed notable names like LeBron James and Luke Kennard.
Kwasniak will play college basketball at Army, where his mother was once the school's all-time leading scorer.
Cornerstone Christian is 17-8 this season with Kwasniak leading the way at 37.9 points per contest. Not only did the 6-foot-2 senior break the all-time scoring record in the state, but he also set the state record for career 3-pointers made last month.
In addition to the career 3-point mark, Kwasniak knocked down his 156th 3-point basket of the season on Saturday to set a single-season state record. He broke his own record of 155 from last season.
