Tom Richey has been teaching AP courses for 11 years. Since 2012, he has been helping students prepare for the AP U.S. History, AP European History, and AP U.S. Government and Politics exams through his YouTube channel. He has published over 300 videos, helping students with both exam content and writing. Although initially focused on helping students prepare for exams, Tom has recently focused on helping teachers understand the requirements of the exam, with a knack for breaking down labyrinthine guidelines into plain English. He completed graduate coursework in history at Clemson University and he and his family still call Clemson home over a decade later. When he’s not teaching, Tom enjoys playing guitar, taking walks, and making an occasional meme.
