This speed drill focuses on subjects that will be required for the journeyman and masters examination arranged by chapter of the NEC. The question slide will still transition in 1.5 minutes and will be followed by the correct answer which will stay on the screen for only 10 seconds. You will have to click on the heading slide of each article section to proceed with the timer. Do not worry about writing down the correct answer during the transition. At the end of the questions, a stop slide will appear and then that will be followed by the questions and answers without the timer so you can review them. You must click on the screen icon in the lower right hand or left corner of the tool bar to start the slide show in order for the timer to operate. You will have a little less time on this drill because the questions are taken from articles and bunched together so find the answer will not take as long.
