THE TUFFEST STUFF CT REGISTRY REVIEW LIVE LECTURE SEMINAR was first offered in 2011 and has been presented more than 100 times in over 80 different venues. Since that time, approximately 2,000 RT’s have satisfactorily completed the SEMINAR and successfully passed the CT Registry Exam on their first attempt. It is worthwhile to note that an important reason for the high degree of success is the quality of the educational materials that no other program provides. THE TUFFEST STUFF is a uniquely successful educational experience.
