1 1 Exam Prep NFPA 70: National Electric Code 2011 Tabs and Highlights These 1 Exam Prep Tabs are based on NFPA 70: National Electrical Code, Each 1 Exam Prep Tabs sheet has five rows of Tabs. Start with the first tab on the first row at the top of the page and proceed along that row placing the tabs at the locations in your book that are listed below. Place each tab in your manual setting it down one notch until you get to the bottom of a page, then start back at the top again. Next to each Tab and Page/Section is the "Reason/Highlight" which is a brief explanation of the purpose of the tab, and/or items to highlight in the section. As you place your tabs, highlight your materials and give some thought as to how the highlighted items will affect you, once you have your license. Special note to our Students: If you are a 1 Exam Prep student, here is how to really get the most from these 1 Exam Prep Tabs. Follow the above instructions, but before placing the tab, find the tab's topic in the outline of your appropriate module. Now locate and highlight several items listed in the outline just before and just after the topic. See how the topic fits in the outline and how it relates as a concept to the broader concept spelled out in the outline. If you take a few minutes to do this, when you take the test, key words in the test questions will remind you of where the information is in the manual!
