Here is some advice on passing the exam

The biggest piece of advice I can go you is to think like a manager, not like technition.

They will give you questions with two correct answers. Always choose the managerial style answer. And know your NIST numbers. I studied for about a week with the official downloadable guide and passed. The experience over the years I have was my secret. And I am terrible at test taking. But this test was all about my last 25 years in tech. Stop thinking like this is all new material. You know it but it is presented in a different way. Stop putting so much pressure on yourself, set an exam date and work toward it. If you don't schedule the date it is hard to work towards the goal.

I hope some of this helps.
