PVIP exams

The PVCMS exam is a relatively new and rumored to be difficult to pass exam.

Most questions on the PVIP exam can be written slightly differently in context to make them PVCMS exam questions, so if you know how to pass the PVIP exam, you will know how to pass the PVCMS exam.

For example, when I recently took another one of the specialist exams, the PV Design Specialist exam, I could not tell the difference between the PVIP and the PVDS exams. I assume that this is much the same for the PVCMS exam.

There are very few people who have taken the PVCMS exam and there has been no activity here until June 2022.

I recommend studying the same as if you were going to take the PVIP exam and I have posted my PVIP exam question here.

If you decide you would rather take the PVIP exam, let me know and we can switch you into that course.
