memorizing the practice questions given in this book

Because this book is a paper practice product, you might want

to complete your exams on a separate piece of paper so thatyou can reuse the exams over and over without having previousanswers in your way Also, a general rule of thumb across allpractice question products is to make sure that you are scoringwell into the high 80% to 90% range in all topics before
