Our unique Study Guide format is used for all but the Math sections. You'll be given a word or phrase and asked to select the proper answer. At first you may not know the answer, just select any answer and the the correct answer will be displayed. Continue to answer or guess at answers and eventually you'll see a question repeated that you remember from the earlier. As you answer it correctly it's removed from the list of questions. Eventually you'll work your way through all of the questions. By repeating a chapter until you get all the questions right the first time (100%), you'll learn all of the answers. It doesn't take as long as you might think. The format was tested on some college students by having them learn the books of the Old Testament. It took them each about 20 minutes to memorize the list.
