One reason you get bored maybe because you have no clear idea of where your study session is going or what you need to accomplish. Plan ahead and have what you want to do in your mind before you begin to study. Layout what you know you need to get accomplished and how long you need to take to complete it. One of the most important aspects to studying is finding the right place. Although you don't want to get bored, you want to make sure you are in a place that is free of distraction. Distractions are counterproductive to learning and will actually cause you to become more bored because you are reminded of the things you could be doing other than studying.
sorry if this isn't the answer your looking for :(
