1 Smitty’s Two Minute Drills
Drill Number 1701: General

2 Instructions When you are ready, click on this slide to start the drill. Each slide will contain a question. The question will stay on the screen for 2 minutes and then a sound will be made and the slide will automatically transition to the answer and code reference. The answer slide will stay on the screen for 15 seconds and then the next slide will appear. Do not worry about the answers during the drill. Once you reach the Slide that Says STOP you have completed the drill. Click on the STOP slide and all the slides will be repeated without a timer so you can manually advance to check your answers.
