Focusing is the skill of directing your attention to the material you are studying. The place, setting or physical location you choose for reading and study determines in part, the number of distractions or interruptions you will have. Choose a place to study where there is a minimum of distraction. If your home or dorm is too noisy, study in a quiet place on campus. Try various student lounge areas, or check out study areas in the library.
Empty classrooms are also good possibilities.
Try to study in the same place rather than wherever it seems convenient at the time. There is a psychological advantage to studying in the same place regularly. As with many other activities, you build a mental association or connection between an activity and the place where it occurs. If you sit down at a table set for dinner, for example, you expect to eat dinner. If you always sit in the same comfortable chair to watch TV, eventually you expect to relax and watch TV every time you sit in that chair.
