Some students require absolute quite while others need some background noise. Listening to classical music at low volume levels has been beneficial in improving the concentration focus of some students. Which ever may be the case, you need to create an atmosphere that channels your concentration on the material to be covered. Proper lighting and a comfortable body position are a necessary requirement. No one can concentrate if they are uncomfortable.
Some students prefer sitting at a desk or table while others study better in a more relaxed sitting.
Chose whichever suits your style but do not become so comfortable that you fall asleep. Before you begin make sure you have all the necessary materials and supplies. Constantly getting up retrieving books, paper, pencils, etc. is very disruptive to your concentration efforts. Have everything organized before you begin and you will be able to accomplish a lot more. Attempt to reduce your distractions to a minimum.
