It depends on which OMPT you want to take.
- OMPT-A, OMPT-B, OMPT-C and OMPT-E: The exams questions and difficulty level are similar to the practice material.
- OMPT-D and OMPT-F: The exams contains open and essay-type questions. Some questions cover multiple topics that require multiple steps to get into the final answer. The practice material gives the basic skills you need to know. However, in the exam you should expect to combine these skills on a more advanced level. See the 3 sample questions for the level of difficulty of the exam.
