Some people are lucky enough to naturally grasp things quickly and succeed in school without having to put in too much effort, while others need to spend endless hours reviewing material in order to learn it. Doing well in school does not have to mean endlessly reading the same thing over and over again until it sticks, as there are study methods which can cut down on study time, and make studying less tedious.
First and foremost, it is imperative to be organized and plan your study schedule ahead. The best way to stay organized is to have a monthly calendar on your wall and make sure that any and all tests, exams or assignments are clearly marked so that you are well aware of when things are due, and do not end up surprised when you find out than an assignment that slipped your mind is due in a day. Next, you should highlight the days that you are going to devote to studying or doing your assignments, so that you give yourself enough time to ensure that you do not end up cramming or trying to do too many things at once.
It is important that you do any and all reading that you are assigned, before showing up for class. Making highlights in your book and taking notes will help you be prepared when it comes time to study. Before you even sit down, open your books and begin to studying, you need to make sure that you take clear, detailed and well-organized notes while in class. By having done your reading before class you will be able to better understand the lesson while it is being taught, and will therefore be able to grasp more. Often classroom lessons highlight the most important points in a chapter, which will help you focus on the main points when studying, as opposed to trying to figure out what is most important yourself.
