International ATMO has two different types of study material to help you prepare for your CHT or CHRN certification exam. They approach the information in different ways; and you may find one approach more helpful to you than the other. Although you might use both to prepare for the exam, they were not intended to be companions to one another. Customer feedback about both of these materials has been overwhelmingly positive.
