How long does it take until testing?

I finished the requirements for my PNP degree in December. The degree will be conferred in February. I submitted all the required paperwork to the state and the school. How long should it take now until I get approval to test? And how will I be informed -- through the mail? Through email? I already signed up for the test on the PCNB website, so all I need now is the notification to take the exam.
