2.  Left click on the presentation ICON located at the bottom of the slide directory to the left of the this slide.  Each slide will transition to the correct answer automatically in 2:00 minutes. The correct answer will transition in 10 seconds. You may also left click on the slide to manually transition.  Do not worry about writing down the correct answer for now. You will have the opportunity to do that at the end of the two minute drill  Good luck  Remember to start the slide show to activate the timer. Copyright 2005 Ted "Smitty" Smith

3.  This drill is a mixture of calculations and code look up questions. You have seen many of them before. Focus on time. Try to find all the answers before the slide transitions.  Remember do not worry about writing down the right answer for now. When you reach the end all of the slides will be repeated without the timer so you can take your time to find the ones you missed and write down the correct answers then.  Click on the slide to proceed.
