AART Exam (Radiology Tech)

There have been a few students at my school who had failed the AART exam. You have three times to take it and then if you fail on the last try you have to retake the entire program again. This has got me worried since this is my back up option if I don't get into RN school. Are there any Rad Tech's here who have taken the AART exam? Is it really hard? Is it multiple choice??
