Book review: How to become a straight-A student "How to become a straight-A student" is another good book by Call Newport. It was written when Call Newport was a high-school student. He interviewed a lot of top-school students to understand their secret: were they so good because they studied harder or because they studied smarter? In this book you can find some useful tricks and acks to study less but better. First of all, the author discovered that the amount of work done is equal to the time by the intensity (W = T x I). For example, if you need 60 hours to complete a work and you do it with an intensity of 6, you will spend 10 hours doing it. But if your intensity is 10, you will need only 6 hours. So, the intensity, your "focus" on the activity, is really important. To improve your focus, you must conquer procrastination. The writer describes some strategies to achieve this goal. For example, it's easier to procrastinate when you are tired and when you have a decreased of psychic and mental energy. So, feed yourself well, sleep enough during the night and don't study for too long. You can study at most for one hour at a high intensity level, then it’s better if you take some rest. The last thing that I want to discuss is the "fluency illusion" theory: some people think that to learn something is enough to read and re-read it. The result of this approach to the study is a false sense of preparation. To improve your study, quiz yourself, explain what you have learnt to your friends, write it down without looking the book. You know something only when you can repeat it to someone else with your own words. This is a short book that you could read if you are a high-school student.
