A basic in life (and study) is the ability to think logically and to uncover and resolve illogical situations. In this book based on the works of L. Ron Hubbard, the student learns a practical approach to logic and how to analyze and resolve situations. The student gains the ability to observe the statistics of an activity, find a statistic that has recently worsened, and locate and revert the change. The student then gets lots of practice applying logic to various situations until he is able to locate a problem that needs resolving and resolve it using the data he has learned. This book and the accompanying learning guides produce a student who can approach a situation logically and is competent in his ability to investigate and successfully resolve minor and major problems in his environment.
