NRPP CERTIFICATION TEST/exam

Hey there

Does anyone have any specific study tips for the NRPP. I Have completed the Internachi adv. course and exam. Did fine enough. But the physics and a great deal of the equation material makes my head spin. I even boight the coursebook for this one…and I feel like I am overwhelmed by the depth of specific material. Anyones advice no matter how simple would be greatly appreciated. Please and thanks, Richard.
