| Here's your chance to see how much of the material in this book you have grasped. There is no time limit for this test but it is not an open book test. (do not look at any reference material) When you complete all the answers click on the Submit Button at the end of the test and your score will be displayed in percentage. Don't despair if you do poorly the first time through. You will have learned what sorts of things you should know outright or be able to figure out with a little thought. You may find it interesting to do the test several times and watch your score improve over time as you learn more of the concepts and material in this book. Have fun. |
