"From day one, I knew Del Bagno/PERI was the right choice.  The study material was very thorough and helped me to feel well prepared for the testing process.  Throughout my studying, each of the staff made it clear that I needed to continue to read at home as well to truly understand and retain the material.  I listened intently to all of the advice that came my way and tried to absorb all I could from the eye-opening lectures.  Needless to say, the coaching truly paid off!  I received the top score on the Sergeant's written exam with a 97!  Thank you, Del Bagno School for Police!
