the material was very good. Easy to follow. the option to take the interim exams for the sections, could have been clearer. It mentioned in the instructions to select the "Next" button a few times, and there was no "next" button to select on that page. In addition, the 35 PDU course stated there was no need for an exam; however, at the end of the course, it was required, I assumed, as it "appeared" you must complete the exam before receiving the certificate. I did complete the exam and passed with a score of 84, and received the certificate. However, I did find the instructions are not completely clear. I did like that the PDUs could be done by PDUnow, and it has helped tremendously for acquiring necessary PDUs for the recurring license.
