I challenge you to make taking our Practice exam(s) a great learning experience. We not only give you the correct answer at the back of the book--we also give you a discussion as to why that answer is the correct answer, and why the other answers are not the best choices. In many cases we take the opportunity to also add additional information so that you learn more about the subject. Have a stack of blank flash cards as you take the exam. Every time you discover some important information, make a flash card so that you can put it to permanent memory before you take your examination. With this great product, you can score in the 90's if you learn all of the information presented. Make sure you take advantage of the TExES Master On-Line Review(s). You know the Competencies for which you need extra help. For example, if you are weak in Math, go to all the TExES Master Core Subjects EC-6 Math Websites. Do a lot of copying and pasting and make additional flash cards. There is a lot of additional information on these Websites.
