I think the information listed in the DSP is pretty comprehensive and covers everything you will need to know. ABPTS states that there will not be any information on the test outside of what is listed in the DSP. There are some more difficult areas to really be able to study for and areas that we had more difficult generating questions about – for example workplace leadership and professional behaviors. Even though this is a small part of the test, those questions still haunt me because they were questions that are very difficult to know how to study for and I think is just something that you have to work out in your head pulling on your past leadership and professional behavior experiences.
