The RRT exam is famously one of the most difficult medical exams, and it requires extensive studying and preparation in order to pass.
It involves two sections — 160 multiple-choice questions and a four-hour simulated clinical setting designed to test your knowledge and problem-solving skills.
The first section requires 62.87 percent (88 questions out of 140 scored questions) to qualify for a CRT credential; however, students must achieve at least 67.14 percent (94 questions out of 140) to be able to take the CSE.
