Test Prep with Mock Exam

Our 2-part Test Prep System based on the ARRT Limited Scope of Practice in Radiography test specifications.

The TEST PREP permits multiple attempts at each question, requiring the correct answer before advancing. There are feedback statements for each option. Students are encouraged to understand WHY answers are correct or incorrect. The MOCK EXAM permits only 1 attempt on each question and students must complete all items and receive a score. The goal is to improve the score until it is 85% or better. This is NOT a guarantee of passing the licensing exam. Students are encouraged NOT to memorize, but learn from this process.

Such a great learning tool!

William from Illinois

“The Limited Radiography Course offered by Control the Dose is an excellent course of study for those wishing to become familiar with basic diagnostic x-ray procedures. I found that the course syllabus was well organized and contained very useful and informative exercises. The mix of practical exercises, textbook readings, and clinical assignments was well balanced and reinforced the objectives. The combination of syllabus, textbook, and AV content makes this course both challenging and enjoyable. It is one of the most professional, well organized, and informative courses available today. It enabled me to take and complete the ARRT Limited Radiographer certification examination and pass with a 95%. Many thanks to Control the Dose for offering such a great learning tool!”
